I think I got it sorted out. I am not 100% sure as I have not cleared the codes and checked it through a heat cycle just yet. I finished it about 30 minutes ago and I am pretty sure it is correct. Here is what I found. I thought C171 was the up stream driver side O2 and C172 was the up stream passenger side O2. I could not locate two wires in the trans harness for C172. I checked the driver side O2 plug and found the wire colors matched C172. I went back and checked the trans harness and found the correct wires for C171. So I went ahead and wired the passenger side for C171. If I understand correctly, the driver side O2 plug is part of the engine harness and the passenger side upstream O2 plug is part of the trans harness extension. If that is correct my connections should be installed properly. The only thing that could be incorrect is if I got the wires for the down stream O2 my mistake, C142?
Circuit 34 is described as "Voltage supplied in Start and Run". Pin #1 on all the O2 plugs. LB/OG.
Yep, you are right. After I thought about it last night I remembered I had pulled the driver side O2 plug and checked continuity for circuit 34. I matched the pin on the driver side O2 to the correct wire in the trans harness for circuit 34. I thought I was going to have to tap into the 42 pin connector but the line was already there in the trans harness. It was just a question of finding it. So the short answer is, I was wrong, circuit 34 is not found on the ECM PIN out.
Thank you Sir, I will give that a try ASAP. Just to be clear, I am only moving one wire on the same pin connector to a different pin slot?
Good deal. I got it now. Thanks again for all the help. It's funny, 4 years ago I bookmarked your user name. I knew we would be talking at some point down the road. You have been a big help.
So true, I have learned so much along the way. Much of the work I have performed during my swap has been the first time for me for such tasks. I could have never done it with out the help of forum members here.
