1985 D150 "Mr. Curtis" race truck with a 2015 6.4

Getting anything to work with the 2015 technology is a great thing. Sometimes i am just happy when something small just works out as planned.
Which does not apply to any of the major exterior lighting features except the front turn signals. The tail lights (stop/turn are one LED lamp, driven by a pwm led driver) not so much.

Headlights and tail lights absolutely demand a proper signal coming back to the BCM over the fault sense wiring. Great.

Well, one is down, several more to go:






I had to rebuild the wiper linkage... all bushings gone, replaced with washers and cotter pins...




The resistors for the headlight switch showed up.
I also ordered a pair of tail light lamps (LED modules, in fact) to destroy them.
I need to find out how they actually work to be able to make a module that can drive incandescent bulbs instead of LEDs.

And i ordered a used wiper motor to figure out how to drive the stock wiper motor... only to find that i had the sense wire in the wrong position of the connector on the BCM.
Yay...


And these are pretty much self explaining:




The really hard stuff will be faking messages from the ABS module to make the BCM think there IS a working ABS module that sends messages.
Like "light the stop lamps".

Arduino to the rescue.
