diagram, never used one so I'm not sure. I figure it out like this:

Take an oHm meter, find two terminals that have resistance then don't have resistance when the key switch is turned from off to the first click

Then do the same to figure out which two have, then don't have resistance only when the key is in the second position.

The factory blue and red should be on the two that work off the first position and your accessory should be connected to the other two.
If you're hooking up lights to the accessory position, power the lights and have the switch work the ground, not the power.
