I bought a used 2014 Raptor brake light on ebay, to put on my FX4, with the wiring cut since I figured I could just order a new harness due it showing on the parts sites. The original owner cut it to splice in an aftermarket tinted light. I am in the same boat, illustration online ford parts is correct to a Raptor 2 bulb and connector but the p/n AL3Z-13A625-A listed is incorrect and is the non SVT 3 bulb harness.
The dealer I ordered from took it back and even gave me a call tag due to the system being wrong. I went to the ford corporate parts site and they say they can sort of see the error, no $hit, but can't investigate for me without a VIN. I just grabbed a vin off local dealer website to use. Was disappointed to go out this morning on day off and install, figured 5 minute project, never easy, soon as I opened the box I could see it was the wrong harness. Dealer said to order whole new assembly AL3Z-13A613-G to get harness for $125, ugh.
Here is a pic from the online vendor I ordered from with the correct illustration but wrong part number, item 5:
