So, I got this crazy idea i want to plug my T-5's neutral safety switch hole so I don't just have the wires for it flopping around under there. It's a neatness thing.
My car has an automatic harness and computer (A9P) so i don't have anything to wire the NSS to anyway. I want to remove it and plug the hole. I'd like the plug to be shorter than the threads on the switch itself so it will bottom out before it interferes with whatever pushes the ball in and out.
With some digging i found out the size is 16MM x 1.5. The thing is, i'm not sure what those numbers refer to exactly. I found some plugs that say they're that size or M16x1.5". Is that the same thing? I don't know. If it was a bolt, I think M16 would refer to the width of the threaded area with metric threads, and the bolt would be 1.5" long. This is what has me confused. The threaded area is certainly not 1.5" long. The length of the threaded area IS critical though.
I've also seen there are oil drain plugs that say they are M16x1.5". Would the best way to seal the hole be to use a gasket for one of these, or teflon tape on the threads?
Thanks in advance!
