NSS & VSS questions

The PCM uses the NSS to know when the engine is shifted from park or neutral to slightly bump the idle. It isn't completely necessary, but if you can hook it up, I would. If you ever need to do a crank relearn, it has to be hooked up so the PCM knows the transmission is in park. As for hooking it up in the harness, it depends on what harness and what tune you are using. An F body harness and tune will use the single wire grounded in park and neutral, where as the truck harness has several wires that go from the trans mounted switch to the PCM. The tunes are different between the two. Also, if you got the transmission with your engine, the shift shaft on a car trans isn't long enough to add a truck NSS to it.

OK, Thanks.

It has a single NSS wire that is Orange with a Black stripe that goes to pin 34 in the Blue connector. The trans came with the engine....
