I have a friend with a 92 ctd and wants to add a tach. Where and what kind does he need to get and how does it hook up.

 

i got the Autometer 2888 from Summit. Sender attaches to the alternator. Then Calibrate.

 

I got a Tiny Tach (from Tiny Tach on line) it's a little digital display and is very simple to install. I put mine on in about 10 minutes. It works great but is not illuminated. Cost about $50.00 if I remember correctly.

 

Yup I got same one

 

that is the same tach I put in my old truck....but the needle moves quite a bit....kinda jumps around at idle...guy said it was because it was hooked to the alternator.....true or faux? redwake

 

TRUE.. mine is the same

 

Try playing with the pickup placement. Mine is rock steady.

 

which is the best and cheapest tach

 

They're definitely not the same ones. I'd vote ISSPRO's for best. The one I have uses a crank sensor for the pickup, no calibration required, rock steady and accurate.

 

I have a 2 inch isspro and it works great. Don't know any details on it though it was there when I bought the truck.

 

Is there not one that hooks up to the factory harness? I thought I had heard of one?

 

ISSPRO has one that hooks up to the factory harness. Some have said you need the adaptor kit, others say it is a waste of time. I think who ever you buy the tach from should have the adaptor kit of your choice in stock. I know guys who have the ISSPRO adaptor, and it works just fine. It wont work without it in my 92. Not sure it will work WITH it, but it definitely wont work without it.

I have the isspro 2in 4000rpm tach pillar mounted and it works great.I ordered it with the harness. marc

 

i have decided on a 2in. isspro tach on a pillar, and hopefully use the dummy plug, w/ adapter. are they alluminated?

 

I have an auto meter tach hooked up to the alt, And i even placed the sensor upsidedown, and still rock steady,
The autometer was new off ebay, I forget the $, But it wasent bad.
