I've been reading up on using my UEGO white wire to replace narrowband functions for the ECU, since I don't have an O2 sensor in my dp. I have a 91 JDM motor, harness, and ECU. I've read 4-5 posts so far, and they're split down the middle. Some say I can splice that wire into the ECU, others say I can't. Can anyone definitively say which way it is? Thanks.
