Firewall Solenoid

Firewall Solenoid
I am switching over from 6v to 12v. I need to get a new solenoid and was hoping for recommendations. Curiously everything I have found has been a four post, but the battery and starter would be on the wrong side so the wires would have to cross. Does anyone have a brand or part number they would recommend?

!? A solenoid is a specific type of relay, it is an electomagnetic switch, right? Starter relay, solenoid, it's all good. We use a small voltage to control a larger voltage/current. That way double ought cables don't need to be run all the way to the starter switch in the cab.
"The terms solenoid and relay can often be used interchangeably; however, in the Automotive market, the term solenoid generally refers to a "metal can" type, whereas a relay typically refers to the standard "cube" style relay."

Correct. It provides for linear actuation through what is called a "motor" or iron core (some call it a slug) to engage a Bendix drive into a flywheel, or operate a door or trunk lid. A starter relay does not do this, it is simply a switch.

I consider Waytekwire a non-credible source for electrical information.
Here is a better understanding.

LOL!
Well I've noticed that you say that about anything that disagrees with your solenoid vs relay assertions, seems be most of them. Please keep in mind this is all in good fun, I noticed you have deeply held opinion on this, so I make an effort to get you spooled up whenever practicable.

Is the above schematic right? It looks to me once the solenoid or relay is connected to the battery at terminal #3 it would be energized thus pulling in the contacts all the time. That's assuming the battery - cable is hooked up and the solenoid/relay is mounted on the fire wall. I think there should be a 4th connection separating the coil from the + side of the battery and that connection hooks up to the starter button, then the other side of the starter button connects to terminal #3. Or am I looking at it the wrong way? Where as contact #2 is supposed to run to a start button, which would then complete the ground when it's pressed and pull in the coil?

And I still wouldn't rely on Waytekwire.
