TPI and Painless

I ended up with a TPI from a 85 Iroc and am in the process of trying to get it ready for installation on my 78 CJ-7. I was hoping somebody here has been through the process. I have the wiring harness,all the sensors and the computer from the donor car. Also I am looking into a painless wiring harness. Any suggestions?

Re: TPI and Painless

Haven't dealt with Painless, I didn't really like the looks of their harness. I bought the Howell hot rod harness which installs under the plenum for a neat installation. It's a bit harder to hide the wiring under there but everything is out of the way.

I've had mine for about 8 years and had a terminal corrode from moisture. I called to order a couple and they just sent them out to me no charge. The Howell also come with a good book with overall diagrams in the back and individual diagrams and a diagnostic flow chart for each error code.

If you want to rework the existing harness, there is a manual by suncoast that will help. Even if you buy a harness, I'd suggest getting the suncoast manual anyway. Just do a google search for suncoast TPI manual.

Being that yours is an '85, now is the time to decide if you want to stay with the mass air flow or change over to the speed density. I kept the MAF, but a lot of people are happier with the MAP system.
