I am putting in an autostart with xk01

I have programmed the remote part of it when I goto program tach learn I am hitting a wall This car brake circuit goes 12volt when car is on and brake is pressed so how do I learn the tach?

I have tried using a jumper from my 12 volt to brake wire and that will allow me into the sequence but once in the command and car running it will not learn the tach signal?any suggestions?

Brake in this vehicle should be White @ the brake pedal switch. This wire should test as +12V when the brake pedal is pressed regardless of whether the ignition is on or off.
