The wiring harness arrived from SteinAir! It includes a new plug for the cooling fan and a short length of wiring from the old plug to the new one.  Looks good.

I moved the sim card from the old connector to the new one and plugged it in. Then I installed the new harness and put the panel back together again. I'm getting faster at reassembling the panel, but it still took all day :-(

Success!!! The GTN fan now runs. Hopefully my panel wiring woes are behind me.
