7 prong plug

installing a new 7 prong plug...can't seem to connect to any outside sources that were listed previously. my front round plug was falling apart and I foolishly didn't make note as to where each wire went. not sure either if it will match my new truck plug the blinkers and stop lights did work before I took the plug apart. 4 wires were totally disconnected. even just a list of wires say from the top clockwise would be good . thanks , bob 1985 1750 I was going to just match the wires on the new plug, but I can't get the tiny Phillips screws out to take it apart, they're stripping

This should help from

Sunline did follow the industry standard wiring setup. Your truck should also be following this. If by chance your camper has back up lights, the round pin in the center of the 7 wire is the back up light wire. #7 labeled auxiliary. Some of the older 80's campers did have back up lights. I do not know what exact years but I "think" by the late 80's and into the 90's they where gone. Wish they had them.

Hope this helps
