Hmm, I've never actually tried the test procedure outlined by Mopar Action in the article. But the color codes at the connector seem to match my wiring diagram. Where did they go wrong?
We have found errors in factory wiring diagrams but do tend to be more correct than aftermarket stuff. So I surely wouldn't trust the YearOne source. Hell, me on the internet is about as dependable as that.
I did say dang near every vehicle of the era. There were exceptions. Regardless of whats printed on paper by who, the color of the wires casing is no substitute for definitive proof. A test lamp should provide that in most cases but maybe not this one where a failed switch is involved.
Sooooo, lets proceed as if we were the U haul worker installing a trailer connector on vehicle. We'll go to the rear 1157 fixtures. The one of 3 colors common to both L&R is park lamp. The other 2 colors are L&R brake/turn. We can take that info and our temporary jumper to the cars wiring harness side of the signal switch connector under the column. Link L&R to what ever color is coming away from the brake lamp switch.
