Pulling the "male" bulkhead connectors

[Bitsyncmaster]

I added a new pin to the bulkhead for the CSV "power" wire so I don't have to have a splice in the engine harness with the starter solenoid wire.

I've got my new wiring and connectors on the CSV, WUR and idle motor. Still have 7 wires to replace in the harness but some of those are in the "valley" so I am waiting till I have the intake off the engine.

I had an engine backfire when cold and acceleration but it seemed to clear up after it warmed up. I did loan my WUR to another owner so it may just be that needed to purge the lines when I installed it. But I will test that again when the engine cools off. I need to verify the ignition timing has not changed also.

My bulkhead wire list is showing C1 for the first cable harness and C2 for the second cable harness. Each of those is "bundled" via heat shrink tubing. I plan to have another cable harness for the remaining wires yet to be replaced. I only plan to bundle those three cable legs with tie wraps.

Found my engine running problem. Turns out the lambda did not get ground. The original bulkhead wire list should have shown:

Blue pin 22 has to go to engine block. It's a wire to the lambda ECU pin 5
Blue pin 23 has to go to engine block. It's a wire to the lambda ECU pin 16

So that was done to reduce noise for the lambda ECU.

Now I need to find a ground for my WUR which was also wired to the engine block.

Here is the fixed word file for those two pins that must go to engine block.

I checked my ignition timing and it's rock steady at 12 deg. I also adjusted the mixture to 40 deg because it was running about 30 deg. I had an idle hunt for about 30 seconds on the cold engine. I will have to check that again when it cools off. I ran my WUR ground wire to the bulkhead metal plate. It was going to the engine block with OEM wiring.
