Yeah, I installed a Pioneer x710bt Nav system in my 2007 Lariat. I used a Scosche wiring harness and also the SW-PSI steering wheel control adapter. Everything works smoothly now, except one thing. My ABS and Parking Brake lights on the dash stay on. I am sure I must have screwed something up, but I have no idea what. Does anyone have any ideas where I could have screwed up?

 

Thanks

I'm not a technician so I am not 100% sure but the ABS light could be on because something may have been upplugged while the vehicle was on. certain things cannot be unplugged unless the vehicle is off or battery is disconnected. this happens a lot with airbag lights. May have to go to the dealer to have that reset.

 

As for the parking brake light it sounds like you need to check the wiring you did down there. it seems like you have grounded the main parking brake wire inadvertantly.
