turn signal switch oddity

[jonesmak1972]

Hey guys,
I am having a problem and don't really know how to solve it. I have put some custom flush mount LED's in a roll pan. I am trying to just use the blinker and not the parking light so I made a spade connector to connect to the blinker portion of the normal stock bumper lights (1972 c10).

These worked before in the bumper but now don't. I get left blinker And no right blinker. On top of this both parking lights light up even though neither is connected to the brown wire of the stock connector.

Question #1 is it possible to just use the blinker portion of that connector or am I messing things up by not providing a ground for the running light circuit as well?

Question #2 in checking the turn signal switch for continuity I happen to check other wires at the same time. With the turn signal in the right position the purple wire also has continuity with the brown. this is not the case on the left side. could this be the issue?




Thanks again for any help
