1970 combo switch wiring

Rick you are in luck. I ordered a replacement switch off of ebay which has the a black wire on the turn signal sw that would connect to the red on the wiper sw. The one in my car the bad one has a red wire going to the red wire. The black wire in question goes to the center post of the white switch on the t/s switch. See the red wire in the middle of Arne's post above. If you want pictures of both PM me with an email and I will send you both.
