I said that option in my first post. SEE: "The only other way......" Smith, you didn't say anything about the tail lights/running lights? I am going by the fact that he has a "new" 7 wire Column switch, and that's how it's wired. That's how it's done on stock TF also. It's not how he has it "set up" that matters. He is asking how to do it. If the instruction says "to hook up the red wire from signal to brake switch, then other pole from brake switch to hot." It's obvious they don't want you to hook the brake lights directly to the brake switch. The AD's didn't come with turn signals, one bulb was wired to the brake switch and one bulb was wired to headlight switch and ground was housing to body, etc. To hook up signals, you have to put an extra function on one bulb AND you have to wire it up per the signal switch instructions. Try hooking up like the diagram and the instructions I posted. OR... see the tech tip By Cletis in the tip section under electrical. "TURN SIGNAL-HOW TO WIRE". We don't know the brand or how many wires coming out of the unit. The poster says we all know that.
NOTE: The Cletis tip deals with Signal-Stat brand and neither wiring chart matches my diagram. My diagram matches the posters red wire hook up per his instructions. He may not have Signal-Stat and may have a brand to be wired as I show.
