The car I'm working on is my dad's 91 Marquis.
The question I am seeking help on is as follows:
Which circuit has 12v with the key in the ON and the START postions, but NOT have power when the ignition is OFF?
I discovered the radio circuit fit two of these criteria (12v ON, no power OFF), but failed to check if it had 12v in the START position.
It would be a great help if someone already knows whether or not the radio circuit fits all three of these criteria.
If it does not, can someone help me determine which circuit does, or how I can find it?
I am working on installing an aftermarket engine management system on this vehicle and need to find a circuit as such.
Thank you to everyone for your all help.
