I've installed a t-rex in my 94 Cobra in preperation for the s/c, and I can't fin'd the wire that I'm suppose to tap into from the harness in the trunk. If I remember correctly, #83 from the relay that I had to mount in the trunk needs to go to a black/purple or something similar, but I've been told that on our cars it's a different color than earlier years. If I understand the directions correctly, I need to find this wire in the harness, tap into it with a test light and the test light should come on for 2-3 seconds then shut off. Tried all of them and none work. Any ideas from someone who has had to do this on our cars?
