I want to run some new, non-brittle wires to my O2 sensor and my BAC valve. the ones are my harness I just put in have seen better days.

My question is if the O2 sensor wire is run directly to the ECU, in other words, can I run a new wire straight from the ECU or does it intersect anything else? same question for the BAC valve.

Sorry, I am not the greatest ate reading the diagrams and just wanted to be sure I didn't jack anything up.

Thanks guys

I think it just goes to the ECU I wouldn't think there is anything esle that works with the O2 sensor. the BAC may lead to the A/c, PS, and other things that increase load but I am not too sure. But it has to get a signal from those things somehow. It could be the ECU tho.

I don't know the wiring for an '89, but it seems like it should run directly to the ECU. The O2 sensor requires a very high impedance on whatever it is connected to, so I don't really see how it could be connected to anything else in the car.
