Swap a 1227747 ECM for a 1228062 ECM - Third Generation F-Body Message Boards

95Z28A4 · 05-08-2001, 02:12 PM

I want to swap a 1227747 ECM into my 1992 S10 with its ZZ4 350 (yet to be fired) with 454 TBI (80lb injectors). The S10 originally had a 2.8V V6 with a 1228062 ECM. The S10 harness plugs into the 1227747 without a problem, but I believe the plug must be re-pinned. Does anyone have any information on the 1228062 ECM? I found a post on the 1228063. Is it pinned the same as the 1228062? I've checked the links below, but I found very little info on the 1228062.

Thanks,
Mike

Hey- I've got a '90 350/700R in my '85 S-10 Blazer with the 1227747 ECM. I found that it's best and by far easier to try to use a '7747 harness out of a wrecked S-10 or fullsize truck, but if you definitely want to keep your harness, email me & I'll send pinouts from my setup if it helps at all.
