Adding a 7-Way Trailer Connector to a 2004 Dodge Ram with Factory 4-Way  

On my 2004 Dodge Ram (which would be the same as your 2003) the factory trailer connector plug split off from a larger wiring harness on the inboard side of the drivers side frame rail near the rear bumper. There should be a rectangular connector…

Yes, it is very possible to install/fit a 7-way trailer connector on a 2004 Dodge Ram 1500. I first recommend looking under the vehicle for a square ten pin connector. This (if present) will be located behind the rear bumper near the spare tire and…

According to our records, the cold brake switch wire on a 2004 Dodge Ram 2500 should be a white/tan wire. Wire color is not always universal, so if you do not find a white/tan wire, you can use a wire tester like part #PTW2993 to determine wire…

My Titan representative tells me that gasket sealer should NOT be used on the #T4820000 replacement master cylinder. The gasket, 4 bolts and the rigidity of the lid ensure a tight seal. Titan doesn't offer specific instructions for replacing the…

I've looked through the various replacement master cylinders we offer, and couldn't find anything that matches your photo. I found out that Reliable stopped manufacturing brake actuators several years ago, and replacement parts aren't…

The part you are looking for is the Brass Connector for Titan Disc Brake Kit, #T4750300. This is the fitting that threads into the master cylinder that accepts the reverse lockout solenoid on your Titan actuator. I have attached a link to this part…
