Parking Brake Light and Stab Trim Light (real throttle assy.)

Hey all,

Has anyone done the Parking Brake Light and Stab Trim Light on a real throttle assy? More specifically, how did you interface it? I know about switiching the bulbs to 12volt bulbs, but what card did you use to interface this?

I have many different OC cards, but I don't have the relay card. So, is that what I need or is there a way to do this with a Relay (from Radio Shack), a 12 volt power supply and say the OC master card or something similar to trigger the relay? What is the output voltage of an OC Mastercard's Led outs?

If you have a different card or way, please post or provide a link if this has been posted before...
