Sorry. the first part of the above post is a quote from 53willys

hmmmmmmm guess I will have to check again but I dont think that connection is on my truck....thanks for your help

My harness does not have the red trigger wire, but it has a grey deutsch 2 pin connector. Where does it go?

It also seems as if I need to split the harness loom. The airdog connection and the filter housing connection only go about 1 foot from each other. I need more than that so that both of the connections will reach. Has anyone else had to split the loom?

Hey YOU, don't go quotin' me cuz I may not know what I'm talkin' about [dummy] [laugh] seriously though

I'm just guessing what to do with these wires and plugs because the directions aren't exact. I was gonna call pureflow today to figure this out. But, came up with my own idea instead. Not sure if it's working? Codes came up on the test drive.

P0628, P0237, P0069

What kind of idea did you come up with?

I am pretty sure you need to wire it the way I labeled it in the pic....there is not a connection to be made on the filter housing....the green weather tight plug on the airdog harness must be for the filter change indicator..thats why it is wired in the loom with the grey airdog motor plug...

just wire it like thisI KNOW FORT A FACT THAT MY 06 DOES NOT HAVE A PLUG FOR THE FUEL PUMP IT MUST BE SPLICED IN!!!!I'm not 100% sure about the 05's but I think they are the same as my 06
.red=is the oem trigger wire on the oem lift pump
two wire grey plug=airdog motor
two wire weather-tight plug(green seal)=fuel filter change light
green= neg batt
red=pos batt
two wires with spade=light connection on dash
your pump will run with no codes if you hook the two battery wires up...the trigger wire(red) and plug the Airdog in...should run with just that.........

I dont have a red trigger wire in my harness though. So what now?

that's cause you have a 03...the 03's harness should have 2 grey plugs..one to plug in by the filter where the filter mounted stock lift pump is/was the other to plug into the Airdog......

you can clearly see that the two plugs (grey with orange seal and black with green seal) go down the frame rail and hook in to the airdog and filter change indicator sensor....This is member "coolumconst" installed pump.....

can you snap a pic of you harness and post it please????

P0628-LOW VOLTAGE DETECTED AT THE FUEL LIFT PUMP
P0237-MAP SENSOR VOLTAGE TOO LOW
P0069-BOOST KEY ON RATIONALITY
sounds like you unplugged your map sensor...and plugged your airdog filter change light into the map sensor????the wires you have hooked up are not right....low voltage on the lift pump is cause you are not running the airdog off the factory lift pump trigger...

No I didn't do what you are thinking. I think the codes P0237 and P0069 have been there since I lost the plastic end tanked intercooler. I never erased them with anything....oops. Now the P0628 is probably something I did. Not quite done yet.

Now something new. Anyone else seen 30+ psi with this pump? I have a 30lb. mechanical fpg and it is pegged after a slow steady climb? My stock pump would always sit at 7.5 psi. I have never heard of 30+ lbs. on one of these. Whats up with that?

something is not right...but I have no idea what you have done????If you wire it just like this then your pump should work just like stock..did you mess with the boss 0-ring fitting on the return line at the AD???I am 100% sure the 05 trucks do not have a plug and play harness...you need to find the Orange with red strip wire coming off your fuel module at the tank....find a place to splice into it...and connect the Airdog trigger wire to the orange with red stripe wire on your truck..then hook up your two battery wires and the grey plug at the airdog...it should run like stock at this point...PM me your # and I will call you and help you right now.....https://www.dieseltruckresource.com/...ilies/cool.gif

does this help???

if you hook these 4 wires up then the pump should work....did you even buy the filter change light kit with your airdog????

Maybe a bad one [duhhh]. I have to get these codes cleared somehow, so I can see if I set the P0628 in the preliminary bastardization of my wiring. [laugh]

As you can see in the picture my harness is a little different. I dont have the red trigger wire. I do however have a grey deutsch plug. Where does this go?

this is how yours should be wired....

Ok...now that I have seen both harnesses I know the way I labeled the harness IS the way it should be wired.....wire it exactly like I showed you you will be golden:cool:

this is wrong...the 05+ harness is the one with the trigger...the plug and play harness is for the 03-04.5 trucks..........if you are not using a single trigger wire, then you have installed the 03-04.5 harness on your truck..not the 05+.

Thanks Mark. You have become an inspiration to airdog intallers around the world.

[laugh] thanks...just trying to help.

So witch pic of the wireing harnesses is for the 05+?

I just wanted to make sure I had a clear understanding of the install before I tear into it, then I saw the pic of the other harness and I got confused. About that time here comes Mark to the rescue.[guitar]

Should be the one with the trigger wire.

Ok thats what i thought just wanted to make sure. Thanks!!

05+ airdog harness

03-04.5 Airdog harness
http://i81.photobucket.com/albums/j2...nesswiring.jpg

That is the 04.5 and up harness correct?
When I ordered my AD 100, there were two third gen options 03-04.5 and 05 up. I ordered the 05 up thinking they meant 04.5 and up. I hope I didn't screw up.

I think you might have ordered the wrong harness...thats the 05+...04.5's take the one WITHOUT the single trigger wire.....
you need this harness..

I have spent the last 2 days trying to get this system installed on my 05. The first hold up was the bracket install. Then the 2 of the fittings had convex innards instead of concave (this makes it really hard to thread them). :( But after a lot of cussing and some serious thinking sessions I thought I was good to go. The truck did start up. I was happy :) then it died :( this went on for a few minutes. then it stayed running for 3 minutes. I thought I was good to go again. I drove out of my driveway and it quit running and will not restart. I got the low voltage code and a loss of ECM communications code.

I made some very simple mistakes. First. I didn't inspect everything to make sure it all fit together (fittings) Second, I tried to follow the instructions to the letter, I cut the black line on the OE tank module plug. I think this is the culprit. Third, I did this on a holiday when stores close and pureflow doesn't answer their phone.

Tomorrow, I will talk to Toby and see what we come up with...So far I am not pleased.

I did this one at least! And tryed to do some creative wiring. Mine never quit though. Still not quite right. Good luck Bro.

Ahh and I can add that my wife thinks I'm a [dummy] for trying to make this stuff up as I go along. As usual. Then she's all impressed when I've figured it out and it's all done........impressed or maybe it was relieved! [laugh]

you need to splice into the orange with red stripe wire on your factory fuel module harness for your pump trigger......that is the only wire that should be cut and spliced....on a 05

if you guys do the wire connections JUST like I labeled and posted with the pics you wont have any problems..with codes or trucks dieing.

After a few hours here and a phone call to Toby I pulled the bed off (MUCH EASIER THAN DROPPING THE TANK), spliced into the orange w white wire on the OE tank plug, rechecked the pickup length, and rerouted the supply hose. I was under a 1/4 tank when it fired up. The truck died 6 times between my house and the gas station (3/4 mile with hills). The truck was filled to the top. I drove it a few miles and I it runs poorly. When accelerating on slight incline it coughs and sputters. The EGTs are 200 degrees higher than pre airdog. I am wondering if there is something wrong with the airdog I got and how much damage I am doing if I continue to drive it...

Man, after reading this I am reconsidering buying an airdog, or any other aftermarket lift pump for that matter. I hope you get everything figured out with your truck.

well that's good, at least I'm not the only one that read the whole thread and said to myself "geesh if it's that hard I don't know if I'll be able to knock that out on my own without help," which is how I'm forced to do everything. [duhhh]

Man that sucks....these installs are not that difficult...take some pics of your install and post them up so we can see how you did it....maybe that will provide the info needed to diagnose this...
did you wire it just like the diagram I posted for the 05+ trucks??
the wire to splice on a 05 is orange with red tracer.....is that what you did???
there is no orange with white tracer listed for the fuel tank module...on a 05????
do you have a fuel pressure gauge??? what's it reading??

this is NOT a hard thing to install[laugh] yes the instructions are not that great...but if you wire it like I posted and plumb it the way the instructions say...you should have zero problems....most these guys posting problems are changing the install procedures...you have to wire it the way I posted....also make sure you are not sucking air some where....did you oil the filter gaskets when you installed the filters???.....did you use diesel safe sealant on ALL the NPT threads??? did you use oil on the pushlock fittings so they dont leak and they push on FULLY seated???
just a few things to check.....

The main difference in the two Airdog wiring harnesses is -

- the oem '03-'04 lift pump is mounted on the fuel filter on the engine, so the lift pump power connector is there in the engine bay - the 'dog harness plugs right into that connector, which controls the relay - the extra wire is not needed

- the '05^ lift pump is mounted in the fuel module in the fuel tank, as is the power connector - the '05^ (and '03-'04 trucks with factory in-tank lift pump upgrade) 'dog harness needs the additional wire for relay control because the oem lift pump power connector is way back at the fuel tank - thus, you'll need to cut the Or\Red wire and splice the 'dog relay control wire to it.
No need to cut any other wires, anywhere.

Make sure you know where your oem lift pump is located B4 you order the Airdog harness

The installation is simple if you simply follow the Airdog instructions -

- don't interpolate
- don't substitute parts because yours are 'better'
- don't leave stuff out because it's 'overdesigned and not needed'
- don't ignore or omit any step(s) because your truck is "special, not like everyone else's", or it will be "not like everyone else's" = everyone else's truck will run and yours won't - and how 'special' is that?

Even a fifth grader could do it, and you're smarter than them........right?

Word up, dudes...................
