Check your boost gauge zero
1. Temporary reconnect your negative battery terminal.

Make sure boost gauge moves to the 0 psi position. Turn the key off. If boost gauge is NOT at 0 psi continue
steps below to re-zero the gauge. If the gauge is at 0 psi - disconnect negative battery terminal.

16. Installation is basically the reverse of the panel removal. Care must be taken to insure the GT’s dash wiring
harness remains behind and clear of the panel mounting points on the dash binnacle to insure that the wires
are not pinched or cut during installation. Use caution not to create too much tension on the turn signal indica-
tor wires when positioning the dash panel for reinstallation.
17. Plug each of the gauges back into their corresponding connectors in the dash.
18. Start with the speedometer end first and rotate the panel into position. Take your time and make sure there
is not any interferences. Do not force the panel. It will take some time, but will work into place. Be very
careful that the wires are free and not trapped or cut as you do this.
19. Reinstall 2 torx screws at opposite end of dash. Lightly tighten.
20. Re-connect main dash multi pin connectors located under drivers foot well.
21. Reinstall remaining hardware and tighten all torx screws. Your Done! Enjoy your new gauges.
