^^^ is how she's been for a bit over a week now. When I went out 23/24-Dec the garage was a balmy 8 C, with the cold snap lately it's about 2 C and is a bit miserable on the fingers and toes being out there. However, even in light of the chill, I've started into the wiring changes today, separating the line to the ECU from the body so it can be relocated to the main JB/battery area.

Good news, it does work!

Pretty straight forward, but for someone following as reference I did the following: dropped the wiring plastic clips to get it free. Then as I removed the tape from the wire bunch gently separated the wires for the ECU connector from the rest of the body harness and reapplied tape as I went to avoid it becoming a loose mess. Only tools were a sharp knife, pliers for the clips, and electrical tape. Obvious note: be careful what you cut!

The main body wiring will get the plastic clips reattached and put back into it's stock position up under the metal lip you can see in the pictures.

I was able to run the ECU wires all the way back to where they come out of the hard plastic unit by the brake booster. This should give enough to run the connector to the ECU if I mount it at the main JB/relay box. The ECU wiring will get bunched and a few pieces of tape and then some plastic wiring loom over it for protection in the engine bay. If I do need to run it back to the stock location I will just run it alongside and retape it to the main body wire bunch.
