Simple Question re Fuel system.

Hi all, Really simple question, I just don't know Installing a 2point immobiliser into a 1996 Nissan 200SX (Australian Spec) Have done everything but can't find the fuel system for the 2nd immobiliser circuit. Is there an easy way to locate the magical wire, I have checked the diagrams on this site, all have been really helpful except for this problem.. If I can't end up finding it, am I better to cut the 12v constant running into the ignition and powering the system direct from the battery? (I am currently tapping into the 12v constant to power the immobliliser). Any help much appreciated

What you want to do is hookup the ignition wire from the ignition harness as your second point of immobilization. That's what i did on the clifford immobilizerTommy
