The wire in question is definitely the red wire in the picture shown. This wire taps into the grey wire on the fuel pump harness as shown. From there it runs into the trunk and then I lose it because it goes into the main wire loom going towards the front of the car. I do not see any red wire in the engine bay and none at the alternator so where would this wire be tapped into coming from the fuel pump harness? I don't see how this is a homemade hotwire kit if the wire doesn't run to the alternator.
