Thread: on-star GMOS-01 adapter

hey guys i just bought a jvc double din adv794. ive done stereo installs before but the directions for the wiring harness adapter don't make sense.

does anyone have a picture of a correct completed on-star adapter for an 04+?

The instructions are on the pac site, what specifically has you stuck?

ok. i figured out everything but the parking break wire. does it need a positive or negative signal to work?

the crutchfield tech line says it needs to be connected to the orange/ white wire from the parking break sensor and i cant find if that wire is positive or negative.
