Hello, Have a few basic questions about installation of Haltech Elite 750, 73 240Z NA. Overlaying the Haltech wiring harness to the existing 240Z harness, can't get my head around some of the connections. First ignition wire (Key switched 12V) Which wire on the 73 240Z ignition switch is the switched 12v (on) ? (B.Y., B.W, W.R, L.R, or G.W) I have a FSM but not an expert on wiring diagrams.  Terminate the existing  ignition wire in the connector and replace with the ECU ignitio
