Wiring MASTERCELL Inputs to the GTM Column

For all of those guys building a Factory Five GTM with the C5 Corvette steering column, here is how you connect the Infinitybox MASTERCELL inputs to the column harness.

Connect these pins to the MASTERCELL inputs:

• Pins D, Z, X & W – Connect to Ground
• Pin V – Horn input to MC
• Pin R – Park lights input to MC
• Pin L – Low Beam input to MC
• Pin K – High Beam Input to MC
• Pin G – Left Turn Input to MC
• Pin F – Right Turn Input to MC

Depending on which turn-signal style you want (1-filament vs. multi-filament), refer to your configuration sheet for the specific wire colors.  You can download the Infinitybox GTM Configuration Sheet by clicking here.
