Can anybody tell me WHERE is the NSS [Neutral Safety Switch] on my 1990 Ford Bronco II ????
Anybody have a Haynes Shop manual with a PIC ?

IT's NOT on the transmission AND IT's NOT on the steering column !!!!

My credo
Do what you can with what you have where you are
Are you sure it is not on the left side of the transmission?

Hi Dennis,
Hi,
Thanks VERY much for the reply & PIC !!!
(was looking for "old style" mechanical NSS on the transmission gear selection/shifter cable linkage [ my bad ;-(( ])

What is the procedure for TESTING the NSS prior to removal/replacement ???? (have a voltmeter [ no Ohms test setting though ]).
What should the voltmeter reading show & how to test IF the NSS is bad & preventing starter turnover ? Do I 'bypass" the switch & test start the vehicle OR other procedure ??.

I have ignition circuit voltage 12.9V (small red wire on top center small post of solenoid) at the solenoid switch (on RF firewall) when I turn on the key start on steering column. (ie. on column ignition switch [mechanical/electrical] is "working" or seems to be working).
Vehicle will NOT key start in P (park) or N (neutral) shift position(s).

[other details] - New solenoid switch; battery at 12.9V ; all battery cells at 2.1V ea; New battery terminals; electrical grounds at firewall & RF fender cleaned & dielectric grease install.
Solenoid switch "clicks" ONE TIME ONLY when ignition key is activated- but starter does not turn over. ( not activated at all).
Vehicle will NOT jump start from second vehicle with battery to battery cables.
Vehicle WILL START strong (every time) when solenoid switch is bypassed. [ + pos battery terminal to +pos starter cable at solenoid ]
PLEASE give details of procedure(s)
Many THANKS
Richard
PS- someone else sent me this haynes manual pic (atteched)

I'm guessing you have tried to start it in neutral...

Could it be that switch that shuts down the engine in case of an accident, that needs to be manually reset (inside cabin I believe)?

Since you can jump across the starter relay and make it crank, the troubleshooting guide indicates to...check ignition switch...and wiring from ignition switch to starter relay
