Grumps,
Does your '54 have the stock (original style) GM accessory turn signal switch?
chevy1,
Does the AutoLamp 9000 have the same wiring as the original accessory switch?
In the 50chevy.freeserver.com site listed above, which diagram is the 5-wire diagram (I see a 3-wire and a 7-wire and a general diagram)?
Grumps,
If you have the original '54 signal switch, I might have a diagram and will post it if I do.
