I have completed my build on my FF roadster IV. Runs and looks great. Everything works except my autometer speedometer/odometer. I have a Blueprint 427 engine with Tremec TKO 600 5 speed manual transmission. Do I need an aftermarket converter for my signal from the transmission to the autometer guage? Thanks.

Shouldn't need a converter. Should hook up directly from the VSS on the TKO. How do you have it wired up? Also needs to be calibrated. Have you tried that?

There is a flaw in the instructions on the RF side. The green wire has to go to the speedo from the sending unit. The grey wire has to be grounded. It says “to efi” but under the setup you describe it’s ground. Ground it and see what happens. You then probably need to calibrate it.
