is there a wire i can tap into that is in the ecu harness that gives off a tach reference? I'd like to wire up my tach but would much rather hook the wire into the computer harness then fishing it into the engine bay and wiring it to the icm.

I believe its a solid green wire, should be in your repair manual schematic

yeah I believe thats the one that goes to the icm but i didn't think it went all the way to the ecu. i'll have to go look for it.

its actually a tan wire with a yellow tracer on the 94-95

and ctgreddy, its pin #4 on the ECM harness
