Excuse me if this has been asked before, but I'm putting a 91 5.7 TPI in a 87 IROC and my question is - Are the two wiring harnesses the same..? I know the motors are different.. MAF SD MAP..etc

Stone

 

They are different.

Have your plans changed?

 

No, plan is still to install the 91 5.7 and I plan to take your advise on changing out the TPI's. I just didn't know which harness to use. I'm worried that I might not have the 87 harness. I knew (after you informing me) that I was going from a MAP to a MAF, but I was hoping the same connector would work.

Thanks, I sure wish you were my next door neighbor. I have like a million questions..lol Thanks for your help, and taking the time to care.. If you send me a way to send you some pics I will..

If you don't have the '87 harness, you either need to find one (might be able to find one on the TGO classifieds", or go to the '91 system. The '91 SD system is generally considered "superior" to handle upgrade mods with tuning, but the MAF is simpler.

Hey guy.. have you ever heard of this...????

Cable X


#68. Install a mechanical tachograph or operate a mechanical speedometer on a vehicle equipped with an electronic speedometer signal (sensor). You can do it -- quickly and easily -- at a cost far below that of buying and installing drive gears in the transmission. You save on the cost of buying and installing electronic tachographs and speedometers.

Cable X lets you use popular, low cost mechanical tachographs such as Abbott, Argo, Sangamo, Servis Recorder and Veeder-Root, and mechanical speedometers such as Autometer, Clark Brothers, Datcon, Stewart Warner and Teleflex. It operates at accurate speeds -plus or minus 2%- on the most common OEM electronic speed signals, and is as easy to install as any electronic tachograph.

You save hours of downtime installing gears into the transmission, and you don't have to mess with troublesome, expensive and long cables. Cost $369.00

 

$300+ for something you can do without spending any money?

No, thank you.

(I bought a Cable X box for my LS1/4L60E swap into an '82 Camaro 6 months ago because putting mechanical drive an an 4L60E ain't cheap. Still haven't got that thing working.)

 

Ok, today had a little time to remove the tail shaft.. tomorrow, going to try to change it out. I was mistaken, I don't have the 87 wiring harness, I only have the 91. My engine is going in a few days.. Stone

 

no big troubles i put the 92 tpi sd setup in my 88 tbi car. dnt really remember which wires i had to move in the bulk head but you need to find both diagrams for that and mark the wires with tape before you move them incase you have to move them back. also the altenator wires different you have to run a extra wire in the 92 harness into the car to make it charge right. Also need to bypass the vats and get a retrofit speed sensor for the torque convertor to lock and get the right air fuel ratio.

 

I really gotta do all this stuff even if it's a 91 TPI 5.7 going into an 87 TPI 5.7 ??????

Stone I'm using the 91 computer too..

 

Hey you turned me onto that photobucket thing.. Let me know if it works.. Stonehttp://s781.photobucket.com/albums/y...rent=photo.jpg

 

That's the "direct link". Try the "IMG code".

 

hows the swap going hope it turns out well!

 

Found a guy that'll just set the motor and tranny in for me for $400 including the rear end (it's from the same 91 Z28), and the exhaust (ditto) next week. Once it's in I can start hooking up the radiator, and all the connectors and fire her UP! Was on another website looking for a rear hatch and other stuff when I came across this... http://www.coolcamaro.cz28.com/photo3.html
