Adding security LED to dash...have some questions
Hi.
I want to add a blinking LED to either my dash or my OHC.....and wire it up to that flashing PATS light. What I'm using is a blue/red flashing 5mm LED....is the power to that THEFT light constant?? Or is it a on/off/on/off/on/off type of deal??
What wires to splice into?? I assume it's part of that cluster of wires behind the radio bezel, to the left.
Also...
What have you guys done?? I know people have added those NightRider security things, and i know someone on here has LEDs flashing in their headlight housings. Basically, I want no switch, and want it to flash when the engine is not running and the truck is just sitting there...just like the THEFT light.
Thanks for any suggestions.

2001~2003 Rangers have a constant B+ power source to the LED. The PCM makes it flash by supplying ground momentarily every few seconds when the key is off or during bulb proveout. A detected theft makes it flash more rapidly.
All you need to do is mimic the same setup. Wire the + side of the new LED to a constant hot - the wire used by the theft LED is white/yellow from fuse 26 to the back of the cluster.
Then tap the negative side of the new LED to the dark blue/green wire that runs from PCM pin 30 to the back of the cluster.
As with any LED installation, if your LED does not have a built in current limiting resistor, you would need to add one of the correct value. Check out John's LED tutorial.
I've been using this method to power 2 flashing LED lock indicators for about 3 years without problems.
