How are you wireing in your neutral swtch to keep the car from starting in gear. I talking about the one in the shifter are you putting a relay and then to the sol. To keep the load off the switch in the shifter. Thanks

Use a solenoid that has a 4th pin that needs to be grounded to function - as opposed to one that's grounded through the case to what ever it's mounted to. Run that to the switch with the other side to a ground. Older stock Chrysler switches work that way.

I use the old single wire Chrysler neutral safety switch, it grounds the stock starter relay.

If you're using a stock Chrysler relay, the #2 wire is the one that runs through the neutral switch.. If you're using a Ford style solenoid, use the 4 pin style.that needs an external ground.

What makes you think the switch in the shifter can't handle the starter solenoid load?

Just run the 2 wires to the two terminals on the starter. B&M shifter.

Most of those switches are just small micro switches of some kind, I can't imagine they are intended to carry any substantial load. And most race cars are or should be running a remote Ford style solenoid to operate the starter, Or if it has factory stuff in it, run the brown wire in and interrupt it with the neutral switch.

So, what's the current draw of a "Ford style solenoid"?

A Ford 4 pin solenoid can be used. I actually use a Cole-Hersee solenoid, this is a heavy-duty, all metal can unit designed for intermittent use. Wires just like the cheap plastic auto parts store Ford style unit. Has the 4th pin for grounding. Use a jumper on the starter and this solenoid carries the load of both the starter mounted solenoid and the starter motor. Main cable at the starter is only hot in "start".

Current to engage this solenoid is just shy of 2.5A.

You do realize that the stock starting system uses a relay right?
The current to activate the stock starter relay is very small.
The micro switch that comes with the shifter is more than able to handle the current required to activate the stock relay.

Yes, I know how the stock system works. I'm assuming the OP isn't using the neutral switch in the transmission or he wouldn't have asked the question. And 3 days ago, I told him he could route the brown wire from the stock relay to the shifter switch and then to a handy ground IF he is using the stock stuff..
