TIPM-7 Fuse Box

The faulty fuel pump relay on many 2007-2020 Dodge, Jeep, Ram, Chrysler, and VW vehicles is the five-pin NEC/Tokin #EX1-1F1J, which is soldered to one of six circuit boards located deep inside the TIPM. Replacement single relays that we utilize for all TIPM repairs since 2014 are the NEC/Tokin #EX1-2U1S. This relay can be used for the fuel pump, horn, and backup lights, with no problems reported. The only difference in the replacement relay linked above is the lack of a vent hole in the enclosure and a small change in the coil resistance.

If you're the kind of person who loves to tackle tough projects like this, keep in mind that repairing your TIPM using one of these relays is no small task. Just getting the TIPM apart can be enough for many to throw in the towel. We recommend that you have soldering experience, especially under a microscope on circuit boards. You'll also need to fully disassemble the TIPM, which many have tried and failed to do without damage.  This relay works on the TIPM-7 fuse box shown to the right.
