I am running into the same issue. Did you ever figure out how to fix it?

 

it's not turned available on all trucks.. i played with forscan trying different configurations when i found a thread that said it might not be turned on. I went ahead and got the FOR-CK11 harness instead

 

some people like to stay closer to OEM because they get a better sense of security that there is more support for it. Me personally? no thanks but i understand it

 

Do you have any direction to the thread? I have gone through with forscan and changed the settings. the factory wire is now receiving power and a remote turn on signal is powering the sub on/off, but I cannot get sound. I've tried using a high level input and a line output converter

 

Did you ever get an answer to this?

 

Just went through this last night. Their wire routing instructions are terrible. There is a factory ground lug on the rear cab wall about two inches to the right on the seat back latch. Is behind the black mat and tight to get to but do able. The length of ground wire is perfect for going over behind the c-pillar panel and up following the green factory wires to that lug. It’s tight and can be done with seat in, but you have to take the seat back latch off to get behind the mat to that bolt and can only turn a little at a time. Or you could remove the rear seat and the black mat cover on the wall and have full access.

 

Hello All,

I have a 2018 STX, I have the WPT-1212 in the C pillar next to the rear passenger seat. I looked into my fuse box and I have no 20amp fuse in slot 22. My question is, If I put the fuse in slot 22 will the WPT-1212 be provided power immediately or do i also need to enable the sub option using Forscan for power to be provided to WPT-1212? I ask this because I plan to use a multimeter to validate of the WPT-1212 is supply power on all required pins , as apparently the 2018 year is hit or miss with this. I am very new to this and read through the entire thread to get a better understanding but I am still VERY new to anything car audio/electrical.

Thanks!

 

If I remember correctly….. On my 2017 12v power was there before I enabled it but the 5v “power on” was not.

 

Thank you D2Abbott! Hopefully my WPT-1212 has the required power to make my setup plug and play.

 

Sadly Fuse slot #22 on my ford has nothing inside to accept the fuse. It just slides in and makes no contact with anything. Looks like it will be running power from the battery for me...

just to verify on a 2018 Ford f-150 STX it is slot # 22 that is labeled for factory amp correct?
