This is the gauge cluster I'm ordering Monday. The Tach signal will come from the MSD Digital 7 and the electronic programmable speedo, will come with an Autometer VSS sensor. Not cheap, $680 shipped!!
Jeff Chambers wired up a factory fuel level float/sending unit on my Glenn Performance deep sump tank. When gauge is on E, I will know my deep sump is still full.
