I have a 2005 197 prostar. the wiring harness has been a challenge from day one. thought i had it working fine but this year when i pulled it out of the barn, the back up lights and therefore backing up, did not work. found a jump from the rear brake lights on the truck going into the harness on the truck. does not seem right. have a 2007 gmc sierra with the 8 point round connector. i pull all my other boats, dump trailers, you name it with no problems. this one has me stumped. should i have been able to plug and go from the dealer or is special wiring necessary to make this compatible. my dealer told me i should be able to plug and go but has not happened. i am in distress here. just learned about the key in the hitch so, i have a back up plan now.............that the boat is back in the yard and off the boat ramp. never received a trailer manual from the dealer. any help would be appreciated.
