Update: after nearly a month and 150+ starts, the only time it didn't work was after the cheap glue I used to hold the magnet on gave up the ghost and it fell off. Repaired with stronger bond.
Still no codes, faults, lights.
I'm calling this a success.
I'll try to make a more detailed diy in the coming days.
