ok, here are the details:
I bought a 2-way remote start system, crimestopper RS7-G5 from amazon for under $80 shipped.

There were 10 total wires that needed connection, including the ground wire. Here are the wires and locations I used in my XR 4100 series LS Tractor.
I will list the in the following order: Remote start wire = Tractor wire , location in tractor
Harness 1:
Horn (yellow) = White wire on the horn switch
Ground (black) = any ground point on tractor
Tach (red/white) = Blue (#2) on the 16 pin connector on the back of the dash cluster
Parking lights (white) = green wire on the corner light switch (below steering wheel) I used these lights instead of the parking lights
Brake Switch (purple) = Green wire, above the brake pedal
Parking light power input (red/black) = I connected this to one of the red wires (part of the other remote system wiring harness) that connect to the ignition switch
Glow Plug (Pink) = Dark Green (#2) on the 12 pin connector on the back of the dash cluster
Harness 2:
12v Battery (red 2 wires with fuses) = Black/white wire on the back of the ignition switch
Starter (brown) = red/yellow on the back of the ignition switch
12V switched Ignition (Pink) = white/red wire on back of the ignition switch
Other direct plug in wires:
LED Light
Push button (small)
Antenna
That's all the connections needed. The default config on the remote start will check the glow plugs before starting, will start in about 30 seconds, will run for 20 minutes before shutting off by itself.
** notes:
I changed the wait time to start to 15 seconds, set it to 2-way remote so it will tell me if it started or not, changed the start button sequence on the remote for 2 presses to begin the remote start system. when you get in the tractor, insert the key, turn it to run (not start), then press the brake pedal to cancel the timer and use the tractor normally.
If you use the parking brake, it will not start because it activates the brake pedal switch.
