Hi there, hopefully posting in the right forum. If not, could a mod please redirect me?

I am installing 4 Hella 500FF off-road lamps on my Land Cruiser. Itís an all new circuit, and I have a single 30A rated dash switch to control them all. Total draw is 55Wx4, or 18.3A if my math is right. All wiring is 14ga off an auxiliary fuse panel in the engine bay.

Given the wiring gauge, Iíd feel better splitting the 4 lamps into 2 9A circuits, but Iíd like to control them with the same switch so I donít have to go through the firewall and install another switch. How do I wire up 2 relays controlled by one switch? How do I correctly fuse the whole install? I assume two15A fuses, one for each pair of lights.

Iíve run across the attached diagram that details my intent exactly, but want to double check here before installing. Having set a car on fire in my youth trying to wire off road lights, Iíve found you canít be too thorough.

Thanks! posted_image

That will work great. Yes, 15 amp fuses.
