Does the light come on under remote start condition? Did you connect Ignition 3 and accessory 3?

and stay on until you drive it. but always check your work and then recheck again.

Did you use reloys to isolate the 3 ignition and 3 accessory wires? Do you have a green wire as mentioned in the note? They show no wire color for Ign 2, I can only assume that it may be green.

If you did not use relays to isolate the 3 wires, try removing the remote start from the equation to see if the vehicle behaves normally with the key. If it does, you will have to either diode isolate (with some high current capacity diodes) or use relays. Are the green and orange wires unpowered during start?
