The smell of burning
New Member
Hi there everyone!
I am wishing to perform a simple hack on my new car which would allow the doors to lock (via the central locking) when the driver's seatbelt is engaged.
I have read the tech manuals on the car and have isolated the wiring which needs to be used.
I am at a loss however when it comes to the actual switching part.
Here is my problem.
Seatbelt engaged gives a 12v output on wire A.
Seatbelt disengaged gives 0v on wire A.
When seatbelt is engaged, this 12v must switch over wire B from 12v to 0v for approx 1 second, but allow wire B to return to 12v (even though wire A is still at 12v).
Can anyone help? I appreciate this may actually be far simpler than I may think, and I am very grateful in advance for all answers.
