I have now updated the relay data sheet that now includes information about the Mini ISO relays with built-in diodes:  http://www.rvsafetysystems.com/Relay%20data%20sheet.pdf .  If you have recently looked at that page, be sure to reload it -- it should have two pages.

Update:  Melbo, the source you list has a very low cost socket.  If you use that socket, be aware that the wire colors relationships are different from my data sheet.

Yes Jim

The white on mine is the ground (coil) the black is the signal in (coil) and the red is the NC and the Yellow is the NO and the blue is the power in or common.

When you say low cost that is true but the quality seems to be comparable to other sockets that I paid over two dollars for.

YMMV

Jim. i think you are right, I think i did tap into one of the relays for power, i was kind of looking at it while i was changing filters yesterday but did not really have the time to trace the wires.  I use 12v magnetic lights on the jeep so i must have found 12v power there somewhere. :)

Hi Jack Conrad,
By using the wiring diagram that you posted earlier in this thread I was able to rewire the relays in our MC8 today and make all the lights work properly on our tow car. Our relays are different than yours so it took a little studying to figure out which terminals to use but I finally figured it out. Another project crossed off the list. Now the one I am dreading is getting the headlights to work well enough to see for night driving.
Thanks for posting the diagram and all the other help you provide, Sam MC8
