My K6 is under the glovebox area. Hinged on a drop down purposed made cage and secured by spire clips. I have been running my EFI since 2010 and been relatively trouble free. One hot water sender kaput, one coil pack with a misfire, Crank sensor tried to make a run for it but overall very, very good.
Changed out for Heritage throttle bodies in 2017 (I think) and that induction roar is fab.
EmeraldM3D are a great company and Dave Walker (company founder) is a guru on EFI and training up a younger guy to take over his mantle.
