hello all,
1989 v2500

While the door panels are off I thought of this mod again, Years ago i installed relays to bypass the window switches and it was an improvement. Now with new weatherstripping they are a little slower.

Wondering,,,, If i feed battery direct voltage to the driver door,,, does that not feed the other 3 doors? Or doors all doors home run back to the source?

I am going to dig out my diagrams but if anyone has done a burb,,, please chime in.

Chris

Looking at my diagram,, a pink wire runs from the distribution block #76 and splices to all four door independently.. (4 runs from the splice)

Why wouldn't i just move the pink wire to a better source instead of running all new wires to 4 doors? Is the OE wire that undersized?
