Hi Rip5, thanks for the reply & advice. What I tried to say was that there doesn't seem to be be power going to the blk/gr/wte 'icemaker' labeled wires. I tested for current with a multimeter, but found none. I expected to read 110v, or possibly 24v or 12v, but nothing. When testing I switched all panel switches, isolators, breakers, etc.. but nothing produced a current in the line. I also tried tracing the wires back, but lost them in the engine room wiring loom. So i either have to start a whole new re-wire from scratch, or find a way to use what is already pre-wired there by Monterey, albeit for the icemaker. Also I assume the Icemaker offered as an option is 110v and not 12v or 24v? Any further help much is much appreciated. Regards, PeterC
