My 1987 IROC's parking brake switch seems like it's "on" all the time. I'm pretty sure that when the parking brake handle is up (out of the stowed position) that the switch connects to ground and sends a ground signal to the instrument cluster to light up the brake light.

My car is under construction (see signature) and the cluster has been replaced with a Holley 12.3 ProDash. I want to program the ProDash to light up "BRAKE" when the parking brake handle is up past the stowed position. This will help keep me from driving off with the parking brake engaged even slightly like I did recently with my LS swapped Foxbody coupe in my signature.

Currently, I"m getting a ground signal from the switch whether the handle is stowed or out of the stowed position. I get continuity from the switch to the connector at the instrument cluster in any parking brake position. Any suggestions on this?
