The ignition and ACC circuits power up but the vehicle will not crank:

If When you depress the brake and the start button starts blinking Check the heavy gauge purple wire to make sure this is hooked up to your starter, If you have a relay inline be sure to check and make sure it is wired properly and is operating correctly.
If when you depress the brake the start button DOES NOT blink, check your brake wire connection, our small gauge brown brake wire needs to receive 12Volts when the brake is depressed.
