i have a 91 w350 and i cant find the 12 valve constant for my radio
does anybody have any idea of what color it might be?

No mights about it, it's the pink one.

Before you go hacking up the harness, why not swing by the local Wal-Mart and get an adapter harness? That will let you wire the adapter to the new radio harness on a bench, then when you go out to the truck everything just plugs in.

i thouhgt about gettin an adapter but whoever had the truck before me cut the original wires as they come out of the harness, and only ran the switched 12v out to both the 12v constant and switched. im putting in an alpine so would it be good to get an adapter?

Nah, if it's hacked up already there's no point in getting an adapter. Happy soldering.

hahah alright thanks. maybe you could help me out a little more. my cargo light and dome light work when they want and my tailights work when they want. ive replaced all the fuses, and now they work about every other time i start the truck up

blacksmoke91

alright i just went out and checked and my pink wire has no power at all
could that be a bad fuse?

wannadiesel

Sounds like a grounding issue.

i get the radio to work if i hook both to the switched and constant hooked to the switched in the truck.

the pink is dead

Then fuse #15 is blown or you have a bad fusible link. (should be orange with a crispy section )

To get around all the factory JUNK, just run the all-the-time HOT to a known source, such as the HOT battery-post; be sure and fuse it close to the source.

On all my trucks, I eventually mount a HOT accessory terminal/post close to the battery.

One big cable feeds this terminal from the HOT battery-post, and all accessories get connected to it, thus keeping it off the battery-cable-ends.

ya thats wat i ended up doing i just hard ran a wire. it was easier in my eyes

There is a guy on fleabay sells reverse radio harness' you can put the correct connectors back on the hacked harness for under $10

No biggie today but subsequent radio swaps will be sooooo much easier IMHO.

wannadiesel

That'll do it, but if you find and fix the problem with that fusible link it will fix your dome light and cargo light issues - they are on the same feed as the constant hot to the radio.

i think i found that out cuz when i connected a few of those cut wires to the 12v my lights started to work. so should i hook theose up to a 12v and that would make them work?
