trying to wire my neutral safty switch and back up lights for my new B&M stealth pro ratchet shifter. i know the blue and green wire is for the back up lights have them hooked up but no back up lights ? ok know i have read on here that the big purple wire under the dash located high up on steering colum is for the neutral safty switch. know do i just disconect the wire and or splice the wire and just hook that wire to my switch that is mounted on the new shifter ? there are two tabs on the switch for two wires to hook up seems i should have two wires running to it as i do for the back up lights? sorry to sound dumb but i have no clue when it comes to wireing. thanks in advance
