Thanks for the info, the coil in mention feeds the hot in run mode for the upfitter switch bank. The relays that are located behind the are all after the switches, I'm looking for the relay before all of this.

Did you check your owners manual? It lists the user replaceable relays. If it's not listed there, then it might be built into the central junction block, and unfortunately you cannot replace those.
