Hi guys ive just wired up my second hand hks turbo timer, the wiring was a 3 pin plug, a ground, and a live. The problem is the turbo timer is always turning the car off after just 5 seconds!! Does anyone know how i can fix this? There is also another grey wire from the turbo timer which i have not connected to anything because i cannot see where it goes. Any help would be much appreciated, cheers.

 

Connect to the handbrake?

My Blitz had a purple wire that you had to connect to the handbrake
