Hey does anyone know if the 88 ecu schematics are the same as the 89+ ecu. Trying to get my DET3 installed and was wondering if anyone knew if they are different or the same. And if they are different could help me out with the wiring. Thanks

Can always verify by checking for the same colored wires at the Ecu and on the engine side and then using a ohm meter to verify its the same wire.

Basically the difference is that the Ecu plugs are different and the 89+ have the hac sensor in the Ecu.

But a 88 Ecu pin out off google maps should show you everything you need without needing the whol wiring diagram.
