I could build this and I might. It's just not something I'd sell because of the liability...

-Wire microcontroller to the brake pedal switch, ignition, and the ebrake switch (brake switches would use 12v relays of course).
-Wire it to an on-off switch for convenience.
-Program the microcontroller to switch the brake and ebrake switches on in the correct order a few seconds after ignition.

You really don't need a microcontroller to do this btw. I'm sure their are cheaper ways, they are probably just beyond my expertise.

Arduino c/c++ that should be close:

Code:

const int ebrakepin = 8;

const int brakepin = 9;



void setup() {

  pinMode(ebrakepin, OUTPUT);

  pinMode(brakepin, OUTPUT);

  delay(5000);

  digitalWrite(ebrakepin, LOW);

  digitalWrite(brakepin, LOW);

}



void loop(){

  digitalWrite(ebrakepin, HIGH);

  delay(10);

  digitalWrite(ebrakepin, LOW);

  delay(10);

  digitalWrite(ebrakepin, HIGH);

  delay(10);

  digitalWrite(ebrakepin, LOW);

  delay(10);

  digitalWrite(ebrakepin, HIGH);

  

  delay(100);

  

  digitalWrite(brakepin, HIGH);

  delay(10);

  digitalWrite(brakepin, LOW);

  delay(10);

  digitalWrite(brakepin, HIGH);

  delay(10);

  digitalWrite(brakepin, LOW);

  delay(10);

  digitalWrite(brakepin, HIGH);

  

  delay(100);

  

  digitalWrite(ebrakepin, LOW);

  delay(10);

  digitalWrite(ebrakepin, HIGH);

  delay(10);

  digitalWrite(ebrakepin, LOW);

  delay(10);

  digitalWrite(ebrakepin, HIGH);

  delay(10);

  digitalWrite(ebrakepin, LOW);

  delay(10);

  digitalWrite(ebrakepin, HIGH);

  

  delay(100);

  

  digitalWrite(brakepin, LOW);

  delay(10);

  digitalWrite(brakepin, HIGH);

  delay(10);

  digitalWrite(brakepin, LOW);

  delay(10);

  digitalWrite(brakepin, HIGH);

  

  delay(100);

  digitalWrite(ebrakepin,LOW);

  digitalWrite(brakepin,LOW);
