Hello all,

I have searched and I have not been able to find the answer. I apologize in advance if I missed it.
I need to deactivate an ignition 12v feed with a negative input. In the absence of this negative input, I need for the circuit to operate normally. Any help would be greatly appreciated.

Tony

BTW that should only be momentary, if it's on constantly it will drain your battery, if you intend using it as an immobiliser I suggest making terminal 86 IGN rather than battery.

Amateurs assume, don't test and have problems; pros test first. I am not a free install service.
Read the installation manual, do a search here or online for your vehicle wiring before posting.
