My coversion from 6 volts to 12 volts is almost complete. BUT, I have one seemingly major problem. I have not been able to remove the heater blower switch or the windshield wiper switch from the dashboard. these two components have to be isolated from the 12 volts as I have installed a solid state voltage reducer/regulator. I need to temporarily remove them , tie them into the 6 volt system installed just for these two motors and then reinstall them. I need some help so I don't bust up the old switches or the plastic knobs on them. The car is a B16B 1961 PV 544. It turns out that the knobs that hadn't moved in 50 years are screwed on. They were tight but with brute strength and awkwardness I was able to get them off. The wiring project is done and now I can move on to the prep work for the engine swap.
