stoplight switch wiring for signals

[DLK]

Guys bear with me as I try to get my signal wiring back in working order. Some of the old posts have been very helpful in giving me an understanding how this setup works. (Greg G's A5700R Wiring Instructions for one).

I have 6 wires coming down the column 2 green, 2 brown a red and a white. The only one not currently connected to anything is the white one. The red one goes to the flasher and the other colored ones go to the front and rear signal buckets.

When I crawl under my car and look at the stoplight switch (by the left rear wheel) I find the BOTH wires to the switch have pigtails - one with a length of wire ending at a female coupling - the other with just a tiny stub of wire coming out of it. I assume there should be a wire from this coupling to the white wire coming down the steering column - does that sound correct? My guess is the prior owner started with the pigtail on the wrong wire - does that sound plausible? So it looks like there once was a wire from the coupling to the turn signal switch - where it went I do not know since I never was under the car to fool with this since the signals worked.

You can see from the illustration that some of the old wiring in my car is quite frayed.

On your stop lamp switch one side should be power from the battery and the other side should go to the rear lamps.

They can be connected to the rear lamps thru the turn signal switch. An easy way to check that is first to check to see if the white wire has power. If not you can put power to that wire and that will light up the rear lamps.

Not sure on the pigtails. I know on my car I have a pigtail coming out of one side of my stop lamp switch. One wire is connected to the turn signal switch to light up the side turn signals and the other wire spliced there goes to my center stop lamp switch. So it acts as a third brake light. Works quite well actually.

Thanks for the guidance , I'll trace those wires to the stoplight switch. For now I have decided to buy a universal turn signal kit and stop troubleshooting the wiring in my column which clearly is not right. Of course one side benefit of the deluxe universal kit is it will give me four-way flashers.

I have thought of replacing the stoplight switch - you can see how old it looks. I suppose if I do I can just bleed that rear brake line after and hope I can get the brake lines off and reconnected without damage.

Dave say it isn't so.... The factory turn signals are so nice with that fancy self canceling.

I've got the 4-way flashers on mine too. Haven't had to use them yet, knock on wood, but they are nice to have. The heavy-duty switch was much better than the cheaper one I bought on ebay.

Ed I am not tearing them out just bypassing them for now. I just want to get the car on the road and don't feel like dismantling the column to find the problem - maybe next winter.

I do not understand how installing a new "kit" will fix a problem. If it were me I would find and fix the problem so I have a good understanding of how to replace the wiring with a new system. How difficult is it to trace 7 wires?
