I recently did a head gasket replacement on my 88 7M-GTE. While testing it for leaks and trying to get it to start, I came across this wire. My friend who has an 87 Supra says he doesn't recognize what that plug could be for. He was supposed to confirm on his but he hasn't gotten back to me so I figured i'd reach out to the community. Anyone have any ideas that can help me out. It is below the lower intake plenum and just in front of the starter. When I crank the car over the starter gets warm so i'm under the impression that it's not a plug directly related with that, but I have no idea at all.
