RPM Switch Help
Hello everyone,
I am attempting to re-install an RPM switch that I used several years ago. This will be used to open the aux ports at the desired RPM (GSL-SE with Haltech). The trigger wire that I could have used to do this with from the Haltech is already being used for the VDI. Anyway, the switch that I have is a discontinued model from Summit Racing. I tried to download the wiring scheme, but the colors don't match what I have. If anyone of you have an older Summit RPM switch, you may be able to help. The red and black are no-brainers. If I remember from years ago, the blue wire and white wire I tucked away, since they didn't have any purpose. The yellow wire I believe goes to the ign coil tach signal wire (YG), and the purple wire goes to one of the terminals on the solenoid. I know I could just wire it all up as such as see if it works, but I just hate having to re-wire/cut/splice more than once. I don't use the stock coils, but I do have the wires visibly available. Here's my thoughts on how this should be wired:
Red wire = 12v switched
Black = Chassis ground
Blue = N/A
White = N/A
Yellow = Tach signal on coil (YG)
Purple = Tach output to Rats nest solenoid. (12v switched to other terminal on solenoid)
If anyone can confirm my thoughts here, I would appreciate it.
Thanks!!!
