I am working on wiring the B&M Shifter into my '73 Mav. I got the BU lights to work perfectly and thought I had wired the NSS on the shifter the NSS wires at the column. Went to test the thing and it will start in any shifter position. I checked the switch and it is engaging/disengaging like it should but it was still cranking. I just spent the last 4 hours tracing everything as much as I could without untaping my entire harness to no avail. In a last ditch, 'for S&G' sort of thing, I cut the red/blue wire that is looped on the NSS side of the stock plug. Lo and behold, it will not crank in any gear. I did a quick search on here and found that the wire I cut is indeed the NSS wiring and I would assume I can connect each end of the wire to each side of my NSS and I should be good to go. Found that info here: http://mmb.maverick.to/threads/neutral-safety-switch-and-bu-light-switch.94380/ My question now is: what do I need to do with the black/white and purple wires I will be disconnecting from my NSS (two wires at the end of the switch in the picture on the linked post)? Can I just cap them or remove them from the plug completely? Or do I need to splice them together? What do they even go to? I've pulled up a wiring diagram and I don't even see these wires on the diagram, only 4 wires shown at the NSS. Hopefully my rambling makes sense here, thanks for any help.
Two wires are for the NSS the other two are backup lights... Apparently you tapped into the BL lights at another point, just cap them seperately...
This is what I'll end up with, going to modify my wiring when I get home tonight. Not sure where the two capped wires go but if I don't need them, I won't worry too much about where they go. I had originally assumed they must be the NSS (since the other two wires were for the BU lights) and wired them up to my B&M NSS but they seem to do nothing.
Well there's your problem right there.. might still be grounded well enough but that's totally wrong spot to mount a neutral safety switch. Wet shoes might cause more issues too. Sorry.. couldn't resist. Use a circuit tester to verify keyed power cycles and good luck with it.
Thanks for the laugh! The handy thing right now is I do not have the transmission or starter in the car so I can test without worry about the thing lighting off in-gear. (and yes, the starter cable is completely disconnected so I don't burn the thing down either lol)
