Ignition on wire

[BoeingDiesel]

Does anyone know if there is an "ignition on" wire source under the hood on a '99? I need to run another relay and I'd rather not go through the firewall again.
thanks gregg

ASD relay in PDC

Thank you Dave, but I'm not quite sure how to interpret this diagram. I found the ASD relay in the PDC but kinda stumped from there. What I'm basically trying to do is locate a 12V power source that activates when the ignition key is turned on

Looks like LG (Light Green/Black tracer ?) fires the coil of ASD when running. When turned off the ASD deenergizes shutting engine off. I would have to dig deeper to find splice 107's location. I would also have to look for LG to make sure of the Light Green statement.

Double post.

LG is Light Green.

So you will be looking for a Light Green/Black Tracer wire. If you can find that splice in that harness you can tap in there otherwise you may be able to find the wire going into the PDC.
