Default Easiest way to wire up a transbrake button

I'm falling on the sword here, when it comes to wiring I'm for the most part completely lost. Can someone explain the easiest way to go about this. This will be without a relay.

On your button you should have a small pigtail. Run trans brake wire to one of the leads off button, then run a 12v source to the other lead off of the button. When you press button it will then close the circuit and send 12v to ththe trans brake. I would probably use a ignition 12v source, ( switched )

You can run a relay and a master switch so you can only activate the t-brake when you want to. The wiring should go like this off the relay.
85-keyed hot 12V
86-to master switch then from master switch to ground.(this will turn on the relay to get the trans brake ready for use).
30-fused hot 12V (run a fuse off of 12v source)
87-to one wire of t-brake to your t-brake switch. The other wire off your 12v switch will go to ground.

Or you can run a fused 12v to one wire on your t-brake then your other wire off your t-brake to a master switch then to your t-brake switch. It depends on if you prefer to run a relay or not.

Make sure the button you use a normally open switch and not a normally closed switch.

and don't forget to ground the solenoid as well

Thanks for all the help guys. I got it wired in and all is well now, just need to wire in the transmission cooler and the build/swap will be completed!
