About three weeks ago I posted a help message for wipers that no longer worked after replacing the dash. I found no juice getting to the switch but had no idea how to solve it. After looking at the wiring several times, there was an orange wire (originally red)from the wiper switch going directly to the oil and amp lights on the instrument panel, neither of which worked also. Along this wire there is a connector, the type that goes over a post, spliced on the wire. This connector was nowhere near anything to connect it to so I initially wrote it off as a previous owner modification of some sort. Big mistake.

I found from the wiring diagram, that the power for the turn signals, wipers, oil light and amp light all come together at the power side of the gas guage, which is the only post and nut connection under the dash.

I am sure there is a proper order to connect all the wiring under the dash that I had no knowledge of, but that wire and connector had to be rerouted to get up to the gas guage and all is solved. It sure drove me crazy for a while but it also was good to finally get it solved.
