Troubleshooting No Power To Brake Controller Using Factory Wiring Harness on Sprinter Van

Published 02/01/2019

Question:

I only have 45 fuses. I think F55 is the designator for the entire under seat electrical center. All the fuses are good but there are numerous open spaces. Can you narrow this down a bit.

The Tekonsha Prodigy P3 Trailer Brake Controller # 90195 along with the wiring harness # 3063-P is all that is needed to add your controller to your Sprinter with Factory Trailer Plug. Since you are not getting power, you should check fuse F55 which is a 30 amp fuse.
