105 B and 105 E on the LS1 harness, what is done with them?
i see above sayin goes to 100 B and 100 E on ls1 harness or is that just referring to the lt1 c105 harness that gets repinned for simplicity.

Circuit 539, C105 pin B (pink wire) goes to a series of other pink wires tied together in the harness. It splits to C220 pin C. It also goes to each of the O2 Sensors. Is this the wire i need to make an individual fused circuit from the LT1 fuse box that powers the O2s? thanks again for the help.

which is why I'm inquiring about the maf sensor wiring. The eng/trans has been installed since January
and it has taken forever to have the harnesses grafted together. Hopefully by Labor Day it will be up and running.

^^Your question is similar to this guys..
From what you are describing this is the MAF/O2 Sensor wire. This needs a fused 12v power from the Fuse Box to function properly.

If you don't want to buy the tools just get a few small cotter pins and bend them open. You have to slide it in from the terminal side to release the lock tab then pull the wire out. You'll also need to remove the plastic clip from the wire side to be able to pull them out.

It SHOULD be stickied..but I think it would take from people's business..
I know of one company that has used this exact guide to make their harnesses.
I hope it helps you guys out..

question for you. I am getting ready to take on the wiring part of the ls1 swap im working on. Difference is its going in a 97 camaro v-6. Car started out auto and we are keeping it auto. How much difference is there between an lt1 car and a v-6 when it comes to wiring? Im using the ls1 harness and the ls1 ecm out of a 2000 camaro SS

Merv i just ran across something today. Would a 98 ls1 engine harness and ecu be easier to use instead of trying to use a 2000 harness and ecu? Besides the temp sensor, which i planned on swapping over to the 98 style, would there be any plug differences?
