Parts Needed to Bypass OEM Trailer Wiring on a 2004 Dodge Ram 2500


I have a 2004 Dodge Ram 2500 with factory tow package. From previous experience, I know that there are undersized relays that feed the trailer electrical. These relays are known to fail. I was told that you have a kit to bypass these relays. Can you direct me to the proper kit? Thank you

If you are wanting to bypass the trailer wiring on your 2004 Dodge Ram 2500 then we do have the parts that you need.

You will want to start off by installing the Upgraded Modulite Vehicle Wiring Harness Kit # 119147KIT. This is a universal kit that will need to be spliced into your tail light wiring and have a 12V power lead run to the battery. Once installed, this kit will give you a 4-Way flat connector for your basic trailer light functions.

For a fully functioning 7-Way connector you will then want to install the Universal Installation Kit # ETBC7.

Should you need a brake controller, I recommend the Prodigy P2 # 90885. This is one of our most popular brake controllers because of how easy it is to install and use.

I have attached an installation video for you to check out as well as attached links to the installation instructions.
