Hey folks, I have a Signal-Stat 900 SigFlare switch from a Mack truck that I'd like to install in my '90 dually. How would I go about wiring this up? It has four wires: blue, red, green and yellow. I assume yellow and green wires are for the left and right turn signals respectively, so of the remaining blue and red one is power and the other is likely for the hazards. But that's only four wires, whereas the factory turn-signal switch has a 10-pin connector - now I know of these 10 pins two are used by the steering wheel slip rings (for cruise and horn) and one is for the wire that grounds on the ignition key tumbler, so these I will not mess with and leave as is, however what about the remaining 7 wires? I was suggested that I may have to run separate turn signals and brake lights (not combined as they are from the factory), however the Mack truck the switch came from had only two lights on in the rear so they must have been combined park.brake/turn lights like our pickups have... Any ideas and/or suggestions?
Heck man, even my torque converter is on a full-manual control and I have to unlock it before slowing down under 30 mph, so I don't think remembering to cancel the turn signals will be much of an issue. Especially seeing how I learned to do so when I learned to drive and it's become second nature, whether the vehicle I happen to be driving needs it or not. For that matter, the cam part of the self-canceling mechanism in my factory switch has been broken since I got the truck, so I already am canceling manually... Besides, if those switches are safe to use in big trucks driven on public roads, they're safe to be in my truck as well
