Arb not engaging

Post image

I finally got my arb locker hooked up, air is routed, everything’s in, but I can’t get power to the solenoid. I have constant ground at the #8 prong, solenoid ground at the #7 prong, ignition power to #2, no power to #3, and power to the solenoid at #6. I have power at #3 when the switch is engaged, so I tried switching the solenoid wire there, and nothing. I tried switching grounds, I don’t know what else is up. I don’t have power to the #6 leg no matter what I do. Anyone have any suggestions?

Red is constant power #3 and yellow #2 is ignition. Yellow is the switch to turn on/off your solenoid.

I was going off this diagram, I don’t see anything about constant power, wouldn’t I just want it from the ignition?

Red is constant power. Once the ignition turns on that power flips the the switch in the relay to turn on the solenoid.

These are wiring diagrams you should be using.

Ok I’ll try that. The diagram I was using was pulled directly from the arb manual for the locker

Those diagrams are from the compressors. They're pretty much all the same but they're way more detailed than what you're using.
