Alright I have posted serveral times with various stupid questions but here is yet another, My motor, I just found out is 93-95 engine, I am replacing a tired out 2.8. I have the ECM for this but not the wiring, so i bought a kit from painless, well evidently Chevy changed the computer from 92 - 93 and my harness is different. Is everything else on these motors the same so i can buy a 1992 ECM and use that or am i going to have to do a shit load of wiring. TO begin with I thought the 92-93 engines were all the same but this has me wondering what else is different

BTW I found full lenght headers from Hedman for s-10's, well 4x4 atleast

What are you putting in, a CPI or a TBI ? I found out the ECM for my
92 Slonoma ST was a "BARM" coded ECM. Now WTF that is I don't
know, but Jet Performance made a chip for it..I have a TBI, and all
the wiring is pretty straight forward. Knock sensor, TPS, MAP, CTS,
EGR, oil sender/pressure, temp gauge, fuel pump relay, trans with t/c
lockup, vss, fuel gage, ck eng lite, ign, o2sensor, injector wiring, and
I that's about all there is. There's ABS on mine in the rear.

If your putting in a CPI, you'll need an ECM for a CPI and the
same yr the better I'd think..If it's a TBI, I would think the ECM for
the 92 would work as long as it's TBI. Good luck

Well, for the CPI, the 92 is a bit different from 93-94 because the 92 CPI uses the 700r4 tranny... The 95 is second gen but uses the odball odbI.5 ecm.... 93-94 should work if you have the proper harness or 92 if you're running a 700r4 tranny (93-94 uses 4l60e)

Hope that helps a bit

yeah its a TBI motor, I am thinking 95 for sure, but that is the comp the vehicle is still OBD I, I think I am going to try the 92 computer as long as ewverything else in the harness hooks up

Yea that's a critical part regarding the trans wiring and what trans
was the orig for the ECM your going to use. I flat forgot about it
anf I just installed a B&M shift kit in my ride this weekend. You'd
think I'd remember that..I suffer from Brain Fade..
