Who knows where the switch that grounds out your starter when you're not in park or neutral and switches on the back-up lights for reverse? Thanks

 

I've done a complete swap on everything on my truck and now it won't start and I checked the diagrams and the only thing grounding this out would be that or the auto shutdown. Starter works, solenoid works, fuse is good and relays are good, it just won't jump the power from the battery to the distribution center back to the starter.

 

Neutral safety switch is on the top of the tranny, driver side... Assuming you have an auto.

Three wires.

 

Ok, so when I have it in park (the transmission is actually locked in park), and I turn the ignition on to "run" the backup lights come on. The break lights do not work. Then when I go to start the truck, the backup lights flick off then resume to be on once I go back to "run" on the ignition. This does not happen when I unplugged the switch I found on the tranny. Odd though, the break lights and the switch worked before all of this and I never had a problem with either, so I very much doubt they all of a sudden went bad.

 

Sounds like a short somewhere in the neutral safety circuit. One wire grounds the starter (middle I think), another controls the back up lights. Check out the wiring section of the FSM.

What exactly do you mean by "complete swap on everything"?

 

From the FSM:
PARK/NEUTRAL POSITION SWITCH (A/T EXCEPT 8.0L) - 3 WAY CIRCUIT FUNCTION

1 L10 18BR/LG. FUSED IGNITION SWITCH OUTPUT (RUN)
2 T41 18BK/WT. PARK/NEUTRAL POSITION SWITCH SENSE
3 L1 18VT/BK. BACK-UP LAMP FEED




Looks like I had my wiring backwards. Pin 1 is the ignition output, pin 2 is the switch sense, and pin 3 is the backup light feed.

Did you manage to get the connector on backwards... Somehow?

 

I took my 01 2wd body/cab/bed and put it on a 98 4x4 360. Then swapped all the dash electricals cause they switched how they were wired apparantly and stuff was shorting and wouldnt work. This is the last step in my project. The only thing that wasnt swapped was the steering column/wheel to 98 stuff, but everything works fine and it trips the starter relay like it should, just shorts the power to it. Ill rig the clip backwards with banana clips to see if that fixes it cause it was clipped in the right way

 

I could test this with a multimeter checking for continuity and voltage, couldnt I?

 

Yep.

 

Ok weird but the backup lights go on when in reverse now.. I just wired up a starting switch because the key still wouldn't trip the starter and it works. Brake lights won't work though.. Replaced the switch and tried probing around looking for voltage and continuity and without diagrams I get lost amid all of the piggy-backing car manufacturers do. Almost contemplating wiring up some with a push button switch from lowes...
