My problem is that the guy I bought my car off of did the swap, but he used the stock KA wiring harness instead of the SR. Not a big deal until I realized that I have a single wire O2 sensor and it sucks ***!I want to hook up a stock 3 wire, but I don't know what pins on the Redtop ECU control the O2 power, ground, and signal.If I can figure that out, I might be able to knock out one more thing that might be making my car run rich as hell!Please help!

The problem i seem to be running into is that I had a redtop S13 ECU #62, and all the info for a heated O2 sensor are for S14's. If I hook a wire up to 115 on my ECU will it be a varible power output even though it's an S13 ECU?Thanks again guys!
