12V relays are pretty standard. 85-86 are control signal and ground. Doesn't matter which is which. 30 is current. 87 is load. Their instructions are completely wrong! This is the correct way. -4 to 12 volt source -3 to 85 or 86, the other one of 85 or 86 to ground 30 to 12 volt source 87 to starter wire It looks like 1 and 2 are for the illumination. These 2 pins are not important. This switch is a piece of junk. If you still want to use it, I would remove your starter switch and check for continuity between pin 3 and pin 4 with a multimeter when you press the button. This is the easiest way to hook it up, but this is assuming the switch can handle 30A. They recommend using a 40A relay but said nothing about the switch's rating. If the switch can handle 30A you don't need a separate relay. Pin 1 - for now don't connect this pin. Pin 2 - connect this pin to ground to be safe. Pin 3 - connect this pin to the Black/White and Black/Yellow wires on the ignition switch harness. Pin 4 - connect this pin to the White wire on the ignition switch harness. The wires you use on pins 3-4 should be the same gauge as the Black/White, Black/Yellow, and White wires. 12 gauge won't be enough for this setup. If they come back and say the switch can't handle 30A then we'll have to use a relay. The idea is to connect the White wire to the Black/White and Black/Yellow wire when you press the button. That's all the ignition switch does. Call them. Ask how many amps pin 2 and 4 can handle max. |
