I started under the dash by rebuilding the heater and wipers. NOS or rebuilt parts...lots of them. I got a new variable wiper switch from JC Auto Restoration in Lynnwood, WA.
(GREAT FOLKS, lots of inventory), but when I put the new switch in, the wiper motor ran backwards, wipers did not return to their resting position when turned off, and Id get a bit of a shock off the shifter console when the wiper switch was ON.
Anyway, I suspected Id miswired the switch. There are seven terminals on it. Ultimately I found out I had a ground problem, nothing wrong with my switch wiring. But, Id gone to the trouble to label a digital photo of the switch connections, so thought Id share it with my fellow 1962 to 1965 Mopar fans.
