Questions re a 91 3.1 Lumina and ading a 4t60e

[KlingonFiero]

Hello Everybody!

I heard about this site from Pennocks, very nice place you all have here

I have searched and searched, but cannot seem to find the info I need...

I have a Fiero that I am going to be putting a 3.1 from a 91 lumina into.

The 3.1 currently has all of the "fiero" stuff, ie: intake, distributor, etc... installed on it. It runs off of the 2.8 computer at the moment and is mated to the 5-speed transmission.

I am going to be putting this engine in my car, but i plan on installing a 4t60e.

My question is this: Will the wiring harness and sensors,and etc... from a 93 Lumina bolt on to the engine? I would like to run it as a DIS engine. As far as I can tell, only the 93 lumina had the option of the 4t60e... and it was a DIS engine only...

If there is some other car i can get the wiring from, please let me know!

I am okay with runnign a distributor, but really need a computer to run the engine and 4t60e trans...

any and all help is greatly appreciated!

[3100 MPFI]

To the best of my knowledge, the ONLY engine that had any wiring different was the 2.8.

The first year I saw with a 4T60-E was 1991 (but I think it was in a twin cam car).

I know that The Cutlass Supreme in 1993 came with the 4T60-E.

As for the wiring, the trasmission wires were on the BODY side of the wiring, and not the engine side. I pulled an engine wiring harness from a 1993 Lumina to install on my 3100 in my 1988 cutlass Supreme and it did not have the transmission stuff.

As for using the wiring, from 1989-1993 the 3.1 MPFI wiring harness for the engines are all pretty much the same. The only real differance I have seen in like the W-bodies will have the TPS and IAC wires in the engine harness, but the N bodies will have it on the car wiring, etc. If you get the wiring from a Lumina, Cutlass Supreme, or Grand Prix, it will all bolt up the same and have no real differances. The only differance I can think of would be with a 1994 3.1 MPFI from the LUMINA. I don't know too much about that one seeing that it was the only 1994 carried over.

Excellent info. Thanks a lot!
