If it helps, here is the RH tail lamp connector. Note there is a circuit (CLS27) that is turn lamp only. It appears in other F-150 schematics but not the BEV as far as I can tell. I attached an example.

Great info, I will look into this. How do I remove the tail light assembly?

Super simple. Open tailgate and you'll see 2 bolts heading to the tail lamp (8mm I believe). Remove those and then pull the taillight straight back. There are some clips that have to come loose. So the first time may be a little struggle.

According to the diagrams there should be a (GN-OG) 18 ECU - TURN LAMP RIGHT REAR, that is missing here (lower left). The (BU-OG) 22 LAMP - TURN REAR RIGHT # SIGNAL OUT is present.

Sorry I confused you. The first diagram I sent you in post 15 was for the Lightning (BEV). It does not have that circuit. Then in post 16, I attached an example of a truck that does have that circuit (CLS27 GN-OG wire). My point was that some F150's have it and was hoping maybe it was present on the Lightning but not used. Looks like it doesn't.

And the SIGNAL OUT circuit CLS54 (BU-OG) just tells the truck that a bulb is burned out. You can't use it for turn signal activation.

Sorry to piggyback on this thread but its somewhat related.

Do you have the headlights diagrams? There are a variety of AUX circuits referenced in the LDCMA module forscan sheets and im interested to find out if there are taps you can use off the main headlight connector to enable auxiliary driving lights.

How is the blinker wired? Is it the DRLs that blink, or the brake lights?

I would like to enable the red DRLs in daytime with Auto selected at the light switch. And then blinking when I am turning (either the drls or the brake lights).

Over here the DRLs turn amber up-front. And the brake light blinks. Also for your trim, there is a light in the mirrors - maybe tie into the mirror?

In the front it always a light on. So I just want to enable the tail-lights to always be on in auto.

I found this in ForScan, mine was set to 1, tried 4, but no change. Maybe there is another setting that should be enabled at the same time?


LR_Stop_Pos_Lamp_Ckt_Usage_Cfg (LRSPLCUC)
726-43-01 xxxx xxxx x*-- 0 = LRSPLCUC NOT_USED
1 = LRSPLCUC STOP_ONLY
2 = LRSPLCUC STOP_POSITION
3 = LRSPLCUC STOP_POSITION_TURN
4 = LRSPLCUC STOP_TURN
