For anyone who has a Dodge Nitro (2007) with factory tow package (7 pin connector). If you are trying to wire in a break controller (Prodigy), I have some info you should find usefull. Black wire on the controller goes to the + battery
post (needs an automatic reset breaker mounted in the engine compartment in between). White wire on brake controller goes to the - battery
post. Blue wire on the brake controller connects to a loose Red wire under the dash. Red wire on the brake controller ties into the WHITE WIRE WITH GREEN TRACER going to the brake pedal switch. Not much info on the Nitro, so I believe this will make the job much easier.
