Thanks for the link...but those kits seem to be for using a Saturn to tow a trailer. I'll have a RV towing a Saturn.
The RV's 7-pin connector probably uses the standard wiring setup. I'll have to dig out my drawings to make sure of that but my brain is pretty tired so it'll have to wait till tomorrow. So tomorrow, I'll check my 12 V fuses, and I know there's 2-3 fuse blocks scattered around the RV.
Think I'll take another look at your link and see if I missed something or if either kit is usable backwards.
Thanks again...
