Diy installer here try to install a viper 4105v2 with flcan bypass hooked up tx rx and 12v power to flcan d2d to the r/s did not hook up key sense door lock/unlock connected horn connected parklights connected. I go to programming of flcan set for d2d then go to 2 key programming do 1st key on light turns red take key out put 2nd key in turn on led does nothing waited 15 mins nothing hold button down led flashes red try doing key again nothing reset samething... Put key in ignition dont do anything just put it in r/s will start car... Do i need the key sense wire hooked up and to which wire the ground when locked / anti grind (orange) on the viper or one on the flcan (dont know which one not listed ) or something else like the pink wire off the flcan needs to be the ignition wire or 12volts constant.... Pulling out what hair i have left please help thanks a million

Ok update do not do this after working a 5 day bender of 3rd shift with only 3 hrs sleep in between ok silly me i hooked pink wire from flcan to constantly hot 12v wow imagine that when it need to be ignition so it would switch on and off to see the key swap wow i feel really really i dont know challenged lol oh well all done and running just have to adjust crank time alittle longer
