how hard is it to install the attitude in the over head compartmnt.

1 Hour Tops.
Pop the blank plate, Pull the OHC, run the wires around the headliner and down the A pillar, thru the grommet, hook up to attitude to the juice. Open attitude, slide into mount and join both halves together. Trim blank plate opening for a snug fit, slide into place, reinstall OHC.

Done!
