Making a little progress with my relay box. I completed version 1 of my wiring diagram. I have to rearrange a few things and then complete the version 2. I'll probably re-write it again a 3rd time to get my wire management down on paper and then start building. Pretty much, I'm going to have a main relay box under the hood that will house the relays and the fuses. I am going to be using axial fuse and relay holders mounted to a metal plate that is then mounted in a fiberglass/polyester project box (by Hammond MFG). The box is about 9" x 9" x 4" on the inside. I'll cut out sections in the plate under the relay and fuse holders so I can run most of the wires under the metal plate to save space and keep it clean. I will have (12) 40-amp mini relays (w/resistors) and (4) 20-amp micro relays (w/resistors). (3) of the micro relays will allow me to customize (3) of the front light relays to require the high-beam be switched on to run. The 4th micro relay will be my "All Lights On" switch relay that will turn on all "light" relays (this is purely for fun) and won't be practical at all. I am also building a small box that will mount inside the dash and provide me a customized configuration for the switches (i.e. keyed ignition, timed relay override, dash illumination, etc...). My wiring diagrams are all for a dual battery setup (power to the accessories will be from an aux battery and all the switch wiring will be from the main battery). Once the fuse/relay box is complete, adding an accessory will be easy. Just run the positive wire from the accessory to the box and tap into the correct spot on the terminal block. Easy Peasy. The incoming switch wires will also have their own mini-terminal strip to tap into.
I just ordered a 6-switch sPOD bezel (bezel only) which will be at my door next week. I wanted the 8-switch bezel, but they didn't have enough in stock. I can always purchase the larger bezel later. The box (main relay) is about $75 (+$10 internal plate) so I'm going to wait until I have all the internal parts and can confirm that they will fit inside the box before I purchase it.
I'd have to say, it's been fun designing the diagram placing diodes here and there to keep current from flowing between circuits. I can only talk about it on here though because the wife wants nothing to do with this hahaha.
