Subject: Back on Tuning, found another issue with o2 sensors by Danspeed1 on 2017/1/19 16:39:11 Hello everybody! I haven't posted in a while so Ill give a little background first. Still working on the slowest C4 project ever, but overall things are going very well. Car was put away for winter but I'm getting the itch to get it back out already and keep working on getting it dialed in. This is a 1990 Corvette that was in a fire... wiring harness, engine, just about everything has been replaced. Last year I got it running and somewhat driveable using moats and apu1. I broke out the car a few days ago and started playing with the tuning software again. I noticed some strange issues with the 02 sensors so I decided it might be worth swapping them out for some updated, heated ones. What I found was very interesting: The drivers side is connected. Its dark in the garage but it looks like a purple wire, original connector still intact. However the passenger side is GONE. No wire, no connector. I started to thumb through the harness, can't find the wire or connector anywhere. Its like it was deleted at some point. Dad states "I didn't touch it." LOL so I can't blame him. Been search Chevythunder for diagrams but to be honest a lot of this has been trial and error if you have been following my posts, the harness never seems to match up to anything on a diagram. Would anyone be able to tell me what the correct wire color of the passenger side, and drivers side (why not?) oxygen sensors are for a 1990 and possibly a 1991 Corvette? If you have any detailed diagrams, or pinouts please post them as well as I can't seem to match up anything to this car. As always your help is greatly appreciated. Looking forward to getting back on this project after months of reading! Dan |
