Alarm wiring question.
Here it is. I have purchased a Option Group alarm Model LD 168-6C. Unfortunatly the install instructions are just a wiring diagram. I have got the power to the alarm and the keyless entry conected and the shock sensor installed. Now it wants me to connects a relay between the Ignition Key Switch and the Ignition coil. I don't know which wire I should be looking for on that one. I also need to connect the Head light system for warning and a Postive and Negative door switch. I assume the door switch is the interior lights. Two more connections one to the Foot brake I assume that is the brake light should be no problem. The last one is to the siren. The diagram only shows one wire to connect to the siren so I assume that the other wire from the siren I should just ground it.
I hope someone has a few answers for this because I don't want to have to guess at this one.
I am installing this on a 1999 F250 Super Duty.
This should be what you are looking for.
I have one wire that is a Headlight on warning connection and the other two are door switch + and -.
