Engine/Transmission (1998.5 - 2002) need switched (igniton on only) under the hood

[Texas Diesel]

I need switched (igniton on only) under the hood to run a 12 VDC device only when the key is in the run position, any suggestions as to where to find it?



TIA

How many amps you need? I only needed about 3A for what I was doing and stole it from behind the radio and ran through the firewall by the drivers kick. Any more current and I would have done same but added a relay with fused load power coming from the battery (that is what I did when i added to the origional 3 amps). There is probably a way to get it from the power dist. center, but I can't figure out a clean way to connect to it.

I need milliamps, just enough to close a relay. I'm trying to find way to avoid going through the firewall.

Cigar lighter is run only, but wrong side of firewall, but an idea if you have to.

i am sure that there is something to connect to in the PDC (power distribution center) that is ignition switched, its mounted just forward the ABS on the drivers side wheel well.

Circuit F18 is ignition swithed and runs into the power distribution center through connector C130 cavity number 28. it's a 20ga wire that is light green with a black tracer. It is the wire that "wakes up" the PCM and ECM. I't protected fuse 9(10amp) in the junction block. I don't the think the controllers woulg miss a few milliamps.

Perfect!! Thanks!
