Hello,

I believe that this would be possible, but I am completely dumbfounded on how to wire it together. Please advise.

I am trying to have a relay or maybe there is something else that can do the trick that could be recommended that turn a lead into +12volts once the car ignition is turned off. Similar to the VARAD Led alarm lights, once the ignition is turned off the lights flash.

I tried to search on the forum but have had no luck. I am trying to wire a shock sensor for my fathers Acura TL due to the increased HID thefts in the area however I do not want the shock sensor to be on at all times, only when the car is off. Please advise.

Thanks

Ken

Use a relay SPDT :

86: Ground
85: 12 volts switched
87: NOT USED
87a: 12 volts constant
30: This will go to the (+) side of the device that you want to have turn on when ignition is OFF
