trailer wiring
Im curious to know how we can tell if there is a factory tow package on on trucks? I know about the trans cooler, hidden hitch receiver, and factory plug underneath the dash for the brake controller. Whats puzzling me is in the fuse box I show a power feed for trailer and it has a fuse/relay in it, but at the rear of the truck I have no power feed wire coming to my 7 way plug. Also confusing is their is a 4 pin flat that my 7 pin is plugged into(no back up wire or trailer power feed) and the brake controller wire coming from the 7 pin goes from blue to a small 16 gauge white/brown wire that does appear to go up to the brake controller.
So I guess my main thing is where would that trailer power wire be if it is in the fuse box but not at the tail end of the truck? Is it a factory extra option not included with tow package? Dazed and confused lol

Ok so come to find out I have a tow package but not the one that comes with the 7 pin wiring. Local trailer shop investigated and found that who ever owned the truck before me put in the 7 pin and a brake controller. Unfortunately they did it incorrectly. Apparently Dodge didnt run the trailer brake wire from the connector up front as well as the trailer power wire, both were terminated at the front fender well. The tech told me they had tapped into the 3rd brake light feed to run the brake controller. So basically the brake controller didn't have any control over trailer brakes, hitting the brake pedal was sending full voltage to the trailer brakes locking them up instantly! He ran the proper wires and all is good in trailer land now lol.

ALL Rams have standard 4-pin. ONLY Tow package trucks come with 7-pin bumper mounted plugs.
Also, I think trailer adapters should be illegal. Using a 4-way to 7-way converter is defeating the entire purpose of the 7-way plug. 7-ways have trailer brakes and are much needed. The fact that someone used that converter to add a brake wire was being ridiculously cheap and sacrificed safety for a lousy $68 which is what the entire OEM add-on kit costs! They prob spent half of that to cobb it up and didn't even succeed.
