[QUOTE="Walt Jaquith, post: 432033, member: 18654"] You don't need diodes. If you look at the diagram of the turn signal switch you'll see that the switch handles disconnecting what's needed to keep current from flowing back through the system. When the left (for instance) turn signal is activated, the brake circuit for that side is disconnected, leaving the right brake light functioning normally while the left light flashes. If I was experiencing what you are--and I was [B][I]DEAD CERTAIN[/I][/B] that I had everything hooked up correctly--my diagnosis would be a bad turn signal switch. Edit: And even if I was dead certain I'd hooked everything up correctly, I'd unplug the turn signal stitch and power the connector's downstream terminals one by one to see what lights up. [/QUOTE]
