do you really need to buy the $64 hella offroad wiring harness?? can't i make my own?
i feel like i can do this way cheaper than the hella nice plug and play deal. i'm putting 4 hella 4000's up on a light bar, the wiring harness says it's good for only 2 lights, so i'd have to buy 2 $64 harnesses for 4 $126 lights!! yeah right. and then i'd have 2 switches for those 4 lights because they can't all be wired to the same switch....i'm guessing it'll get to hot?? i don't know. how have you guys wired your auxillary lights, what relay's have you used, where are you drawing your power from, where are you grounding? i need some light bar basics/aux lighting basics...any help or explainations would be greatly appreciated...thanks alot.
$64 for a harness is too high, KC's wiring harness is priced at less than half of that and they are essentially identical. A 3 second search using www.froogle.com/ produced this... http://www.google.com/products?q=KC+...Search&show=dd where you'll see several at $28.99 on the first page, maybe there are more for even less past the first page of that search result.
Good enough, that confirms you need two relays since you want to run four 100 watt lights. A single pair of 100 watt lights draw pretty close to 17 amps and a relay is only rated to around 25 amps so you'll need a second relay for the second pair of lights.
