I understand where the shop foreman is coming from. It's easy for one who is unfamiliar with electricity to install a fire hazard. Also, adding stuff may void a warranty, or have a negative impact on resale value. The thing to do is to plan the install, using the appropriate wire gauge, and appropriate fuse, plan the wire routing to be professional but not permanent, draw the whole thing out, and present it to the foreman. He may be inclined to let you, after all. If you find a rubber plug that you can pop out, poke a hole in, and get a watertight seal around that wire entry, offer to purchase your own OEM rubber plug. They're not expensive. He may be inclined to let you, if you can convince him that you know what you are doing.

 

Oh, good. You're half-way there. Just remember, the larger the wattage, and longer the wire run, the thicker the wire that is needed. Make sure that your access point will accommodate both wires. Use the following table to assist you in wire gauge selection:

the best wire i've found to run to my inverter from battery are welding cable. heavy rubber coating and heavy gauge wire.

 

If I wanted my truck interior more like home I would install drywall.
