Left side brake woes

Thanks for your input I will try this on my next go at it.

According to my diagram there are two white wires at my TS connector harness (which there are) and one goes to the flasher switch and the other to the brake light switch. A diagram of the flasher switch would also be helpful. Wiring diagrams are great but it kinda falls apart when you dont know how the switches are supposed to work.
With the links in above post #20 you should have more than enough info to diagnose it. good luck
