Hi Bill,
Yup, I knew I had the relays. I'm deeper in the weeds because there was a trailer power adapter added that I'm trying to get rid of. I'm pretty much under control EXCEPT that I can't figure out how the Euro/American switch was originally wired. It's a SPDT switch that takes the brake light signal and sends it either to the brake pin of the 7-pin trailer connector (Euro mode,) or to wherever it gets split through diodes to the two turn signal pins (American mode.) I'm starting to think there was an original "3-wire" adapter in the cabinet that fed the left and right turn signal wires to the 7-pin connector on the hitch.
Any ideas?
Thanks!
