Default OK, I am an idiot!

It is important to share the stupid mistakes we make. If nothing else it will give some a laugh, but then it may also keep others from making the same mistake.

I was tired of the rat's nest of wires the previous own had left under the tank of my 29 tudor to support the turn signals he had installed (picture 1).

So I rewired and install a new turn signal switch. Now there is just a single black woven loom going from the switch over to the kick panel. MUCH BETTER! (picture 2)

The new switch came with a wiring diagram showing where all the different colored wires went. Thinking it would not matter, I just made sure any color labeled right went to signals on the right, and any labeled left went to signals on the left.

I was correct FOR THE SIGNALS! they all worked perfectly. UNTIL I STEPPED ON THE BRAKE! My right rear brake light did not come on, but my right front signal light DID! It turns out the turn signal switch also powers the brake lights. Who knew!

So I had to remove the kick panel and rewire the switch making sure the wire labeled right rear went to the right rear. Now all is well. So don't be like me read those directions AND FOLLOW THEM.

I do have one question about the turn signal switch. the lights on the switch itself don't light up as the signal flashes. This is not a problem since I have a beeper on my flasher. It is not a ground problem since I connected a separate ground wire to the switch and it made no difference. I am thinking that this switch (bought on E-Bay) is designed for negative ground systems and the internal lights are getting no power on my positive ground system. Any thoughts? Will the switches sold by the venders for the model A light up properly on positive ground systems?
