Aye for now MSD DashHawk is coolest data you can get with just a plug in vs something like a DEFI hud which requires the DEFI link controller. It's cheese compared to the DashHawk.

The HUD needs probably a different harness to be put in at assembly and of course it needs a new dash pad and module. Then you plug that into the harness so it can talk to the computer.
