New XP900 Wiring Question

I just got done doing this project,,there is a couple ways to do this,,i only ran 1 pos and one neg #8 wire from the battery up front under the hood area to a 100 amp breaker to a 80 amp constant on solenoid switched on by key with the lug under hood from the factory to a separate fuse box,and from the fuse box to the hole that's marked out in the firewall running everything on separate fuses and the fuse box has a place for all the grounds too ,,,,this was the easiest way and safest way that I could think of for running lights heat and everything you want

They are plastic push darts. Take a flat screwdriver and gently pry the plastic center up, you don't need to pull it all the way out, then remove the whole push dart when it becomes loose.

I had drilled a hole on the drivers side of the firewall and added a rubber grommet... The dealership crowded the passenger side when they ran the winch wires and did a piss poor job. I did however run my main power and neg wires through the pass side factory grommet . All accessory wires are on opposite side. I was absolutely clueless on wiring relays and switches when I started.... Patience and several private messages to fswan , and now I've been going around telling my buddies that their junk is wired wrong.... There is great people here, that will go out of their way ...we are truly lucky

A few more pics of my plate I made... I originally intended to bend one up but decided that keeping it flat and adding spacers underneath would give me more surface area to mount my fuse block , relays and battery issolator.
