Hello
I have a 2008 Bounder (38P) workhorse chassis and I need to replace the rear trailer plug. I am not sure of the best way to start. Should I cut the wires and splice the new one in or what? Any help would be appreciated.
The reason for the replacement is the plug is cracked and broken.
Thanks

I think you would be better off disassembling the old one and removing the wires one by one, or if you feel the need to cut the wires right at the back of the old plug so as to not shorten anymore than need be. There is generally a little excess length in the original harness. Then put the wires directly into the new plug without splicing. If you can avoid splicing you would be better off. You can find many photos or schematics for standard 7 pin wiring on the web. Take your time and you'll do a great job.

That is the way unless you want a new cable all the way to the front. I guess you would have to answer why you are needing the new plug. If something stopped working the plug may not be the problem

Here is a diagram of the wires there is retainer screws that holds the plug in the mounting it has to be removes then it will slide foward unscrew the wires noting the location on the old plug not all the time the color code is followed there are colors and numbers on the plugs

If you do need to splice, be sure to use heat shrink tubing around the splice to keep out as much moisture as possible.

Do not splice as there is no need to if the wire is good to the bad old plug, or if you have any extra cord. Do like habitat guy said and take the old wires off one at a time, then slide the new housing on and rewire the new plug one at a time. If you don't have a chart just write down the colors to the position and do the same on the new plug. Be careful as the trailer hot supply is hot all the time on most, but not all rigs. If you ground it accidentally you will blow a fuse or breaker. Good luck!
