Hello All I am trying to figure out what wire is what. I need to install a Road master Brake Pro 9300 Proportional Towed Car Brake Unit in to my 1993 Jeep Wrangler 2.5 5 speed

I have attached the type of connector I need to tap into.

This photo is the switch side, the plug/harness side has 5 wires two white ones ties together. I tested all the wires on the harness side of the puge all 4 and and they all have 12v on them to ground, so I am a bit confused as to which wire send the power to the brake light. I need to attach the brake pro 9300 to the wire that send the signal to the brake light to activate. I am unable to find a diagram for the type of connector I have. your help would be much appreciated.

P.S. I hope this made sence

I can’t help you with what you are asking but I can give you a simplistic solution. This is the brake controller I use when towing with my Jeep and it’s awesome and requires no install.
