Thanks all, Natcho, I found your schematic on the 3 wiring options, I used #3 and ordered
another 5 pin relay, but after looking at the wiring and the initial test I did,
I think we've lost the 12 V supply.

It's been awhile since we drove at night, and we've done some alterations to our wiring in the interim, so
we'll start there.

Thank you all,

Joe
