12v fused from battery to relay 30 pin, ground on 85, ignition on 86, and output to switch on 87. Open the fuse box under the hood and use a multimeter to locate a fuse that is activated when the ignition is turned on. One you find that, run a wire from that fuse to the 86 pin on the relay There is a rubber boot on the drivers side near the steering column on the firewall which where I cut a small hole. Fish the wires through the hole with an old antenna or other stiff piece of wire. Once that is done, select how many switches you want and where you want them to be. Don't cut any wires until you have the desired length. Once you decide where you want your switch(es) drill the hole to size and put the switch in place. I advise using a 30 amp with and indicator light switch, especially if you plan on running the lights for long durations. If you run constant power without the relay to the switches they can get hot and melt. Power, ground, and output will be the three pins on the switch which are pretty self explanatory. Decide however many light you want per switch and link the red power wires together. You can use butt connectors or solder. I always use solder and heat shrink to keep moisture out. Link the ground wires together and secure them to the frame or negative battery post. Run a power wire from the lights through the same hole in the firewall to the output on your switch. Secure wires with split loom and zip ties then you're done.
