2002 Nissan Sentra Viper 791XV

There's an orange on the main harness with the parking lights, etc. Itis a ground when armed. The orange on the small little 4 wire (pink, purple, blue, orange) is a -ve accessory output. The whole reasoning behind using a normally closed circuit (30 and 87a ) for starter kill is to make it "failsafe". If the brain decides to crap out, you will still be able to start the car with the key. The way you want to wire it (normally open) will cause issues if the brain decides not to send out the grounding signal for the relay to close. I'm not understanding this: ....so 85 gets grounded? or 12v?...i know 87 gets 12v constant, and 86 gets the 200mA trigger (on/off)...and 30/51 is the output For the second starter, wire as follows: 85- -ve second starter output of XCRS 86- some source of 12V that is there during crank (IE: not an accessory) 30/51- fused 12V 87- second starter wire of car Now, to kill this second starter, asyou are doing a starter/alarm combo: 85- Ground when armed (primaryharness, H1, pin #1. orange) 86- ve ignition 30/51- key side of second starter wire 87a- Car side of second starter wire.... you will also attatch the second starter output that you built with theother relay here as well. Gus Wherever I go, that is where I end up......
