OK, I have the computer out and the harness pushed back into the engine compartment. I am going out on a limb here and saying the other large connector above the computer (on the passanger side) and also going into the engine compartment carries the connections for stuff like oil pressure, temp gauge, tach, spedo and that kind of stuff. Is this right? Larry

The engine/ecm harness contains the clear double connector that is the 203. The 203 connector has the +12 for the fuel pump relay, VSS wires, A/C, TCC, and a few switched 12V wires.

The other bulkhead connector passes through to the engine side as well and routes over to the 500 connector. That connector has Oil pressure, temp, tach, fan, starter wire, coil power, and backup lights

The other passthru includes all the wiring for the rear of the car. You need to keep it if you care about things like tail lights and fuel pumps.

Normally swaps leave that alone and only connect at C203 and C500.

If I leave the passanger side connector untouched and pull the driver side connector and the computer, do I have to add anything else to make this thing run? I notice that the one I pulled had two relays on a plate wired to it on the inside of the engine compartment with a connector to the air filter. I took the plate off the FW and left all attached to the harness which is sittion on the engine now. Larry
