Been looking for a decent wiring diagram for an 89 Olds Toronado Trofeo. Haven't found one on line yet. Specifically looking for the ECM pinout for # 88999198.

Thanks.

I checked a copy of the GM ESI from 2005 and it doesn't have any diagrams or info for any 1989 Olds or Buick. You might have to buy a manual. HTH

I bought a Haynes manual. It lists the colors of the wires but not the terminals. There's a couple of wires that do repeat.

Lesson learned - Haynes and Chilton manuals are garbage. Should have got the factory manual off ebay.
