Plug and wire.. This is what I got, figure some of you LSX guys would know. It is a 1999 LS1 Harness, the spot where the 3 plugs go to the Relay Box off of the Harness, it's the single Black Plug with about a 14ga purple wire off of it. We traced it to the Relay box, couldn't get anywhere from there. Any of you guys know what it is?
the purple big gauge wire just goes to the starter relay on the starter, and then to a relay controlled by the BCM. If vats is clear and passed, then the bcm will put power to that relay when you turn your key to the start position.

I had an idea it was that..the LT1 car has that under the Dash cause I think it goes to the interior relay box. The LS1 car is on the Fire Wall. Any ideas on if it actually goes to that in the LT1 car, we are looking into it.
