I have a 2018 GMC Sierra 1500 with a 6.2L engine. I want to install ham radio gear. 1. Auxiliary Battery Tray exists. I will buy AGM battery and clamps. 2. I have West Mountain Radio ISOpwr (Auxiliary Battery Isolator) to connect between main battery, aux battery, and load. 3. What I need is an off-the shelf wiring harness (battery to battery) with install directions, or suggestions how to route the harness that I build 4. For the load, I plan to use approximately 10ft of #10AWG. 5. Can you suggest where I can find part numbers, and/or install directions for adding an aux battery in the engine compartment? thanks for the help
