Wiring diagram for the Multi-function switch

The switch itself only tells the body control computer left/right or hazard flasher. The lights themselves are controlled by the BCM.

If turning on front and rear signals is acceptable the wire colors are dark green for left turn, and tan for right turn. Apply ground to either wire activates the lights if the key is on.

If however you are trying to set this up like a toad for behind a RV, you will probably need to hook in a relay to each actual bulb in the rear to get turn signals because of all the computer modules in between that would need to be powered while towing.

Check out the diagrams (Below). Let us know what happens and please upload pictures or videos of the problem.

Okay, for that you will need to run new wiring and relays to the rear as well as make custom light circuit boards with logic circuits to fool the BCM into thinking the lights are working as they are "supposed" to work, otherwise the BCM will start setting codes and warnings for lights being out.

GM uses a single feed to the logic boards that control the lights. The turn switch tells the BCM "right turn" and the BCM sends out a data signal through the CAN bus that tells the right hand light modules to turn on. Entirely different wiring system than the Lincoln.
Basically there are no individual wires for turn or brake, just the computer and logic boards. The boards get told "stay on" for brakes or "flash" for turns. Both power and ground are constant feeds to the boards. Just the control signal changes.
The only lights that are controlled the "old" way are the markers, those are fed from a relay out through the brown wires, but that gets its signal from the BCM as well.

You might be able to use the trailer tow circuits to do what you want but not sure how you would convince the BCM that things are normal.

I have attached all of the wiring and option wiring diagrams plus the trailer wiring.

Okay, they did export that vehicle, there are different wiring diagrams and taillights for it for export countries. Look around a bit and they should show up. If you look at the wiring diagrams it shows some of the export options.
There are also some lights on eBay that show amber for the turn signals using stock wiring. Might want to see if a dealer can get the export version for you. Could save a lot of work.

Alpha,

Are you working on the same vehicle or just have the need for all amber on one? If it's the same vehicle the above information was all we received at the time. I suspect that kgbs used some aftermarket lights to do the conversion but I'm not sure.

They are flashing fast because the BCM isn't getting the correct feedback and it thinks the rear lights are out. That is one of the issues with the way they are integrated into the vehicle now. What method did you use to break them out of the brake lights?
