I have look all over for this. I bought a Chiltons book and they did not print that year in it. Can't find one to match my wiring this is a truck ecm and harness. A1 Dark Green white strip A2 Yellow black strip A3 Light Green A4 Tan black strip A5 Blank A6 Blank A7 Dark Brown A8 Blank A9 Blank A10 Blank A11 Gray A12 Purple B1 Blank B2 Red B3 Blue B4 Pink B5 Light Blue B6 Green yellow strip B7 Light Blue white strip B8 Red B9 Gray B10 Blue B11 Brown or black B12 Green C and D are 32 pin

i have the full electrical system manual from a 90 with tpi info - if you think that will help i can post it. pm, and i will if you want.

Thanks but I think it will need to be a TBI 91 92 93 with a 7060 ecm.

TPI is not the same

Ive got the pinout in my 92 service manual, Ill see if i can dig up a camera, otherwise Ill type it up in excel

Row A & B are on C1
Row C & D are on C2

Your posted colors are way off

(Your posted colors are way off)

Thats what I can't figure it looks like its a factory harness but the colors don't match anything I can find. Its a C1 24 pin and C2 32 pin. This harness and ecm does not use the spark control module like my 86 TPI has.

No wonder nobody can find anything in the diagrams and manuals for our F-bodies, this ECM is from a truck, as BlueMax stated in the beginning.
Our TBI engines use the '746 ECM model.

I'd recommend looking in a Chilton's for a truck or you could search Chevy truck forums to find one online.

Hope this helps.

mine are the factory wiring diagrams for ALL mods of that year. the book has tpi, tbi, everything. i dont think they changed all that much - except the people who put things together appear to have reversed the colors in the power mirrors.
it was 35.00 well spent - they downloaded all of the diagrams, color pics of the wires, everything.
but if you dont need them - that is kool, i was just offering.
i posted the general diagram at http://www.thirdgen.org/techboard/te...hing-91-a.html (Turn the key and nothing 91 gta) see if you think it can help and let me know.

or maybe this is more to your liking. vin e is the tpi or is it f - well you can have both. we have to look out for each other.

I bought the Chiltons book it has all but the years 91 92 93. I was reading a few places on here about people using the 7060 ECM. Was just hoping some someone had the pinout. Thanks
