Can anyone decipher the wiring for this DPDT relay used in the kill switch. I am not that conversant with relay wiring (std relays Ok, but the DPDT has me baffled in this diagram)

The link for the complete setup is

Wire 12vdc to one side of the coil

Wire the other side of the coil to ground, through a magnetic switch

Now you have two sets of contacts:

Contact A:

C - (-) side of coil

NO - to ground through a NC pushbutton switch

NC - No connection

Contact B:

C - 12VDC

NO - (+) output to drive 'Heavy duty automotive relay'

NC - flashing LED (not actually necesarry)

The LED is used as a visual indicator to let you know if the immobiliser is activiated or not.

And thus not actually needed to make the system function as designed.

Thank you for your replies. I will put the system together tomorrow to see if it works as described.
