i found this one it should help. note that the colors are not the same from 4 to 7. I have re-wired several trailers and each trailer has its own little quirks. the most helpful tool through it is a test light. I always go through and test the truck first to make sure everything is working properly on that end then move to the trailer. I learned that one the hard way i spent a good 30 minutes trying to figure out why i couldnt get one of the trailer functions to work and come to find out it was a blown fuse in the truck i had it hooked up too
overall not a tough job just take your time and double check your connections. i recommend using the heat shrink connectors to keep water and corrosion out. Let us know how you make out
Thank you so much!
So I will not have to run any additional wire, and rewiring a 4-pin to a 7-pin should do the trick?
I will let you know how it turns out once I can get around to doing it!
*CORRECTION: After reviewing the diagram you posted, I see that I will have to run an additional wire for the 12V portion of the plug.
This is not a problem as I will run it straight to the interior lights (each have a switch) and also to the exterior spotlights (which I will install a switch for each as well).
Thank you again, this is a HUGE help!
