Conversation Between bigtexan99 and 07MIDBOXHD

Sorry, just got your message. Did you figure it out?

I seen where you added "both" harnesses for a 04-08 sub.
I did the same but need some power help.
Where and how to hook up the big blue wire.
I have the 07 xl and oem o7 f150 Nav added.
My nav has the sub hook up but sub not enabled in diagnostics.
You seem to be the only one who added "both" harnesses for front and back.
