We just installed an s-trim on my 94 Cobra and left the t-rex for last. The instructions say that wire #83 from the relay they give you should go to a black/purple wire in the stock fuel pump harness located in the trunk. I was also told that this wire is not black/purple in the 94/95's. If I understand them right, the directions say to tap into this wire with a test light, turn the ignition on, and the test light should stay on for 2-3 seconds then turn off automatically. I've tried all 4 wires in the harness and get nothing from the test light. Can someone who has already had to do this tell me what wire I need to tap into. This is all I have left before firing it up. Thanks much

On my 1995 gt the wire is brown with a purple stripe. Hope that helps.
