Installed eBay/Chinese 21-23 Raptor Style LED Taillights

[5.XOH]

Yea I don't think the XLT has the trigger wire (my 24 xlt didn't) for the turn signal since it uses the brake as the turn signal. You will likely have to run wires to the BCM if you want it to work.

Looks like the sets I’m buying just aren’t wired correctly to understand the FORscan changes. Or maybe I need to get the exact set OP purchased.

I attempted again today, and can see the changes affect my stock light, but the aftermarket one does not function correctly.

Back to FB marketplace I go!

I think the lights are fine, it is more than likely your truck does not have the rear turn signal wire because the XLT uses the brake light as the turn signal. XL and Lariat and above have a dedicated turn signal from 21-23.

Look at your stock plug, the 4 pin one. Does it have all 4 wires?

If you want to know for 100% sure you can look at the C2280E connector on your BCM. The rear turn signal output is pin 26 for the left side and 52 for the right . If you don't have a wire there then it will not work unless you tap into the fronts.

Stock connector attached.

Good, unplug it and use a multimeter on the orange and grey wire to see if it has voltage when you use the turn signal. If it does then you're good and will need to check the adapters that came with the lights to make sure they are pinned correctly.
