Customer Q&A - VSM 900

I Have a jeep CJ5 1972 sparton turn signal switch 6 wire can't find one. Can you find one or something that will work.

Unfortunately, we do not have a 6 wire turn signal switch.

Hello, have a '79 Kenworth needs this signal stat, is this one 6 or 7 wire? I see 6 in photo, pretty sure I need 7 wire, maybe I'm missing the other wire in pic above? Thanx, Dan

This is a 7 wire turn signal switch. Grey Black Grey/Black Stripe Yellow Blue Green Red

Is it American made?

Yes, VMS900 is made in the USA.

Have a new VSM 900 6Volt Turn Signal Switch and installed the switch on 1951 Ford Pickup and have all new wire harness and it worked for all little then all at once it blows fuse's as fast as you replace them what could be my PROBLEM.

Without physically inspecting the wiring its difficult to say where your problem is coming from. There most likely is a dead short somewhere in the wiring. You can contact our service department if you purchased the turn signal switch from us and we can try to help you troubleshoot the problem. Thank you!
