I am in the process of rewiring all of the aftermarket electronics on my car. I am using a separate fuse box that comes straight off the battery and using a relay to switch the power to the box. Anyway, before, i had my uego running into the engine bay and getting the power from the little blue connector. I was then sending the signal to the MS through the stock o2 sensor wire. My question is, what pin on the ecu does that go to? I want to eliminate the uego wiring in the engine bay and just go straight to the ecu with it.

 

Per The Documentation, it can be connected to pin 10 of the center conductor (requiring that you cut the stock O2 wire going to the MSPnP) or it can simply be connected to the stock O2 wire.

In your '95, that would be the red/blue wire (with a shield around it) going to pin 2N of the ECU connector:

 

Yeah, i saw that about pin 10 but i didnt know if you had to change a setting to get it to read from pin 10 instead of the one on the stock connector. Now that i think about it, i assume the stock pin and pin 10 go to the same place. Thanks Joe!
