Since you have a Dodge truck, there is a plug under the dash that is pre-wired for a brake controller. You can buy the adapter for about $10 that plugs into that adapter and wire it to the brake controller. You may need to put a fuse in the power cable going to the battery but some already have the fuse in the holder.

On my 03 Ram 1500 I ran a new wire from the battery to the 7 pin connector because the factory wire was 12 gauge and I was getting 12.5 volts at the 7-pin. I ran a 10 gauge and it jumped to 13.4 volts.

All my Ford/GM trucks had to be completely wired.

i think alot of it depends on if it had a factory tow package or not, as to if it was pre wired or not.

incedentally.. on my dodge ram.. i ALSO ran a seperate parallel brake wire to help out the one in t he truck harness..

Found the harness that came with the truck. Joined the red, white and blue wires but need to go get a 20 amp breaker before I can finish the job.

Thanks again for the pointers.

All Dodge trucks have the wire harness under the dash. The tow package adds the 7 pin connector to the rear and the class III hitch.
Also, if you can't find the red wire at the rear of the truck, sometimes it was cut-off under the truck, directly below the drivers side seat.

i know the plug would be there.. but if the truck was not specced with a tow package and no 7 pin plug is at the rear, will the actual wire harness be ran back there? I know there is a tap for a 4 pin flat.. and with that and power and brake power you have all you need.. etc..

I found most Dodge trucks have the charging and brake signal wires all the way to the back but some have those two wires (red and blue) cut right under the drivers side seat along the frame rail.

at least it's better than the old days of having to tap the brak switch.. or get one of those converters if you have the backwards style switch..

Give it a break. Ford and GM along with all the imports have had the wiring in the about the same time Dodge did.. Get off the dodge band wagon....

Sure they did, when you PAY EXTRA for the towing package. It was not on every truck like the Ram's/Dakota's.
