Safety neutral switch

This is what I have in the car now:
Painless 5001 8 circuit wiring harness.
Switch panel I made myself.
the wiring harness is a relay activation.
So I have the switches wired to the relay activation harness.
.


You mean Painless 50001. Sadly, I find their documentation ambiguous and poorly written

Run the ground wire from your relay 86 to the NSS. That will or should provide the ground path for the relay.

Yes, the relay box from painless "should" give you everything you need if you can figure it out.

IF you download the "Painless" destructions for the 50201 switchbox, PURPLE no14 is "start"

Then look at table 6.2 of the destructions for the 50001 That purple hooks to harness connector terminal 11

So that fires the relay in the Painless box

The output seems to be purple no10 wire no 870 "starter solenoid"

What they don't mention that I can find is how to incorporate a grounding NSS with the Painless start relay.

I'm sure cracked is correct. Pull the box apart so you can access the bottom of the included start relay.

Bosch relays have either 4 or 5 terminals depending on whether they are "normally open" (closed with coil power)

or whether they are SPDT (three wire switching, IE center wire switching to two contacts.

In the below diagram,

85 and 86 are the relay coil. One of these is grounded and the other goes to your starter push button. You need to find out (in the 50001 box) which terminal is grounded, and BREAK that ground, and run that relay terminal off to your NSS

IF this is strictly an "on/ off" relay, 87A may be missing. It is the "normally closed" contact

"Heavy" power will be coming into the relay at 30

87 will be the purple wire run off to hook to your Mopar solenoid.

An ALTERNATE way of doing this, if you decide to use the BM switch, is to put the BM switch inline with the starter push button on the way to the input of the relay box.

And of course you can run the purple to your factory start relay and hook the original NSS up as per factory, to the other start relay push on terminal. I see nothing wrong with this. Mopar start relays have been pretty reliable, and it gives you a nice big stud for power junction
