97 Rodeo trailer wiring problems

I have a 97 V6 3.2L Rodeo. I can't seem to get my boat trailer lights to ever work correctly for me. My friend hooke up his truck to my boat trailer and all the lights worked for him. I have bought the tail light converter kit and it still doesn't seem to work. No turn signals, one break light, etc...
Does anyone have any ideas to help me out?

I would start with a test light to see what is going on.

I live in Madison too!

I checked the continuity of the converter and the only one's that continuity are the ground and the Tail/Marker. The turn signals don't work.

This is the third converter that I have bought in as many years.

Is there any other way to hook the lights without the converter?

I bought mine from JC whitney's, plugged it in and it works.

no wires to cut

Does the harness from jc whitney plug into the factory isuzu plug that is meant for a trailer wireing harness? or does it tap into the tail lights like a universal kit?

Plug into factory taillight connector. Standard 4-terminal connector plugs into trailer wiring. No wires to splice. Look factory installed. Weatherproof, long-life plastic housing.
(A) Connector includes built-in taillight converter.
(B) Connector includes built-in power taillight converter.
