toad lights don't work

[bandmbrown]

2008 diesel bounder - jeep wrangler toad - cool tech harness.
the passenger side turn signal doesn't work and the running lights don't work.
driver side turn signal works.
thought for sure i installed the harness correctly so replace the bounder with my boat tow vehicle which has a 7 way plug. use the same 7 to 4 adapter i use on the MH and the same connector cable and...everything works great.
replace the boat tow vehicle with the MH and same problems occur.
the 7 way on the MH is a chrysler plug-in attached to a quick connect that has a bunch of little connectors the go to the front end of the chrysler connector. no corrosion anywhere.
got to be something in the MH.
any suggestions.
thanks

Take a test light or multimeter and check out the MH wiring at the plug. May have bad wiring.

Most new vehicles have seperate fuses for left and right side lights, as well as for the trailer wiring having seperate fuses from the chassis. I had the same issue before leaving for Thanksgiving and found a fuse blown.

Definitely check the fuses first. You will have two sets; one is for the 7 way only.

any idea where these fuses will be on the bounder. example: under the chassis or inside the vehicle or in line with the wiring
