Hi, i need to know which wire is the signal wire on the fuel pump of my deisel combo van. I am fitting a tuning box to increase power. The tuning place told me that one wire has to be connected to the fuel pump signal wire so that when it registers the increase in fuel required when driving the tuning box kicks into action! Any ideas on color of the wire and where is it situated??
