the 6-pin connectors and pinout are different (Stark is a JST-JWPF and the Alta is a connecter I don't recognize they use on their harness) - I am hopeful and it seems logical that Hirschmann would make the same throttle for both. I documented the Alta pinout. Plan on testing the Stark throttle on the Alta as plan A if needed. Interesting that Alta engineers used 2 different voltage ranges for the throttle sensor outputs. Guessing to make it easier to identify which sensor?
