So today I finally tackled the Wiring bulkhead. The plan was pull the wires I didn't need out of the bulkhead and drop them inside the car. Later when I redo the interior I was going to follow them inside and unpin. I had already cut the wires I dint need short to make the process easier.
I took the bulkhead apart separated the wires into keeping and deleting. I then started to pull the out of the wire separator that clips in the bulkhead. That's when I noticed allot of the wires had a twin. I remember thinking when I was cutting the wires I dint need out "why would all the sensor wires run inside when the ECM is in the engine compartment". I decided to get my meter out and ck them.
I learned a lesson today, I could have kept my TPI harness intact and maybe sold it. Out of the 50 or so wires in the bulkhead that come from the ECM 30 are pairs that run in from the ECM go about 5" then loop back out of the bulkhead back into the engine compartment. When I was done only 4 wires went into the engine compartment that I didn't need. I put heat shrink on the ends and tucked them in the harness.
Here is a picture of some of the wires that loop back. You can see the sticky crap they seal the bulkhead with about half way.
