wow, nice vale replacement. that is totally awesome.
i hate wiring messes like the one just pic'd. i have had to determine which wire was the correct one out of about 20 that were the same color. i really hate that as all i had to work with was my multimeter. the wires were being spliced into from my end in a reconstruction job. the 20 wires were dead and i was powering to them to continue onto valves.
that was a slow process, but i got er figured out in about 15 min or 20 min.
