 The donor wiring diet

I asked a for some feedback on the forum about  the difficulty of removing unneeded wires from the donor wiring harness.

Several folks responded and said it took a long time but they thought it was worth it. So I thought I would give it a try. They call it the wire diet.

Based on their feedback I bought an Electric and Vacuum Trouble Shooting Manual on the web for about 35 bucks.  It was worth every penny.

Another really good suggestion was to put the harness on a large board.  I used screws and tie wraps to keep the wiring in place as I removed wires.

Speed control, power windows, wiper controls, courtesy lights, rear window defroster, seat belt  chimes, radio, A/C and heater wiring were all removed.  It is a very slow process.

I started by labeling connectors and everything I could identify.  I never new there were so many relays and solenoids in a car.

When all was re-taped it looked a whole lot smaller and why not.  I probably removed 10 pounds of wiring and controls.

What I did not show here was that I repeated this process for the wiring harness that goes from the computer to the engine compartment. I must admit I did not remove as much from that harness.

Hint: I am finding that I am having to untape and re-wrap some wiring because I did not leave enough length in some of the wiring branches.

BUT the question is, did I remove too much?  Will the car start?  Stay tuned.... I don't know the answer yet.

It took about 21 hours for the wire diet. 10 pounds in 21 hours.... now that is a diet!
