Wiring up lightbar question

[Kd0603]

Ok ive got a loom with a h4 adapterso i can plug and play
Ive also got a dashmount switch instead of the stupid pushbutton one these looms come with
But as i got a factory dual battery set up on my rig which battery do i wire the loom to looks like the pne on the drivers side mighy be the starting battery as it has more wires hanging off the terminals

Hello, if both batteries are factory crankers you can use either one. If you get to the point of too many wires coming off you batteries check out a fuse block. Makes it much neater.

I'd wire them from the driver's side battery. That is the main cranker if you want to fit an isolator
