Wiring up the KC's

[78Suburban]

I think I'm gonna run all 4 off of one switch. What size relay should I use? their website's wiring kit says 40 amp, I guess that's a good size

I'm also going to put an inline fuse about 2 feet from the battery. I guess 30 amp would be a good size? I'm going to run 12 guage wire.
Anybody wanna share any ideas with me? Are there any reasons I should cosider using 2 swithces controlling 2 wires each, instead of what I'm planning?
thanks,
James

If you are going to run all 4 at the same time, you might want to consider running 10 gauge. 12 awg-20amps, 10 awg-30amps, 8 awg-40amps.

You need that relay for TWO Daylighters. If they're the sealed beam type, they draw 150 watts each. 150x2=300 watts/12 volts=25 amps. You can power two relays from one switch, then feed two lights from each relay.

I think they are only the 100 watt kind. So do I still need two seperate 40 amp relays, or can I just use one 40 amp relay for all of the lights? I guess using 2 seperate relays would allow me to use 12 ga wire instead of 10 though?

I would still go with dual relays. That gives you the option of going with even brighter bulbs later. 130 watt H3 halogens cost about the same as the 100 watt ones.
