I work for auto parts store and the guy in the shop convets an EXCEL 7127-3 to a signal wire internally 7123S. It can be done externally by taking a wire from postive terminal to the b side of the double plug (futherist away). The 7123 style fits gm v8's 73-86. The single wire is commanly used by farmers on tractors because it is "self exciting".
