Turn signal/brake light/tail light issues

Just for reference concerning the switch and harness.

That's the one. The adapter is necessary as the connector end on the switch is a different type.

Ok, cleaned up the ground at the tail lights and I still have intermittent brake lights but I do now have turn signals that work. And oddly enough the dash signal lights are now correct, saving me taking the dash bezel off yet again.

69 dash bezels are evil!

Yep, the light switch ground has plagued many a troubleshooter. DC current is quirky, you can do everything you should, but new stuff tends to "burn" a path with the circuit, then somehow the gremlins go back to sleep. I get these every time I do a complete.
