ECM Wiring

Does anyone know where I can find a wiring schematic for an ECM computer in an 84B2. My project has only one of the o2 sensors wired in and I need to figure out where to get my wire for the second one. Or does anyone think this will cause problems if I leave it as Is. Just Dropped the recently refurbished 3.8L in last night hope to have it running on the road by this weekend.

you should be able to find the diagram in your repair manual, from the donar car/truck. I would recommend just using the harness and ECM from the 3.8 and just make another hole for the other o2. if you can use the y pipe from the 3.8 that would work well.
