2024 Chrysler Grand Caravan SXT (Rebadged Pacifica Base Trim): I’m looking for advice on the best way to route inverter cables from the battery to the interior of the vehicle, preferably on the passenger side or, if necessary, the driver side. Ideally, I’d like to do this without drilling. Is there an existing firewall passage that can accommodate two 2 AWG cables? Thanks!
Running inverter cables from the battery to the inside of a Chrysler Grand Caravan SXT can be accomplished while minimizing the need for drilling. Here are some steps and tips on how to proceed, particularly for the passenger side, though the driver side can also be an option:
Locate the Firewall Grommet: Start by looking for a pre-existing grommet in the firewall where other wires pass through. This is usually located near the battery on either side. Check the area near the battery on the passenger side for a rubber grommet that can accommodate the cables.
Using a Wire Loom or Grommet: If you find a suitable grommet, you can carefully pull back the grommet (if possible) or create a small opening in the grommet for your cables. Make sure to seal any openings afterwards to maintain weather resistance. If there’s not enough space, you might consider a larger grommet which can securely accommodate the two 2 AWG cables.
Running Cables in the Cabin: Once through the firewall, run the cables along the side of the vehicle under the trim. You can usually tuck the cables under the plastic trim pieces that line the floor and side of the vehicle, securing them with zip ties if necessary to prevent rattles or movement.
Avoiding Tension Points: Be mindful of areas where the cables may be pinched or damaged, especially near any moving parts or sharp edges. Ensure they don’t interfere with pedals or seat mechanisms.
Securing the Cables: Use cable ties to secure the cables along the path you’ve chosen, ensuring they are kept away from heat sources, sharp objects, and moving parts.
If you do not find a suitable existing grommet, you might consider accessing a different area of the firewall that may offer more room for running cables or consulting with a professional who may have methods to help without drilling. Always remember to disconnect the battery before starting any wiring work to avoid any electrical hazards.
If you’re unsure, it’s advisable to consult your vehicle’s service manual or seek assistance from a professional installer to avoid any complications.
