While I had the fenders off after mocking up the cutting of the holes for the roll cage to go through the fender tops I installed an accessories fuse box and relays, these are to run the big light bar and front led spot lights as well as power for the thermomfan etc, will also have room for any addons after the fact..
I'm running a separate relay setup for the new LED headlights, this relay harness uses the original headlight wiring only to trigger the new relays which then supply a good solid power feed to the headlights, this takes a good deal of load off the factory wiring and switches as it no longer needs to pull too much power through the factory stuff...it also gives better lighting as the headlights now gets good solid consistent 12v and plenty of amps..
