Recently changed out some air conditioning Components on my 2007 ford f one fifty pick Had to unhook the computer briefly? And when I got it all put together. The security indicator light on top of the dash is on solid. And when I turn the key all the way everything goes dark. And there is no communication with the computer

 

What wiring did you disconnect when performing the repair ? Sounds like you left a ground wire off somewhere or it has a bad connection.

 

I unhooked the 3 connectors from the computer what would cause the anti theft indicator light located on top of the dash to remain on constantly in all key positions?

 

What year is your vehicle?

 

it's a 2007 f150 fx 4x4 extended cab
