XDP HD Relay to Grid Heater Wires for Dodge (1998.5-07) 5.9L Cummins

The XDP HD Relay to Grid Heater Wires are a direct replacement for the factory relay-to-grid heater wiring on 1998.5-2007 Dodge 2500 and 3500 with the 5.9L Cummins.

XDP lists the kit as (2) longer relay-to-grid heater wires wrapped in a single loom, (1) ground wire wrapped in loom (for some applications) and (4) black alternator covers. The wiring comes pre-loomed and is built to replicate factory routing and appearance. It cross references to 37529.

The grid heater pulls serious current during cold starts, and these wires live right on top of a hot engine. Over time the factory wiring gets brittle, frayed or heat damaged, and you end up with weak grid heater operation, hard cold starts, or worse. If you are in a cold climate or the old wires look rough, this is a smart refresh.

Disconnect both batteries before removing the old wiring. Clean the terminals at the relays and grid heater, tighten all connections securely, and route the loom away from sharp edges. A loose connection on a grid heater circuit builds heat fast.

Backed by a 2 Year / Unlimited Mileage warranty, it is a clean, factory-style fix for one of the most heat-abused circuits on the 24-valve.
