2 questions
I have a 99 LS1 ECU from a holden commodore in australia
now i'm just trying to finish the wiring and i've been stalled on the speedometer
1) i have pin 20 & 21 which are "HI" and "LO" respectively for VSS, these are drawn on the diagram and make a circuit via the VSS sensor
now where i'm stuck is i'm retro fitting a dakota digital speed sensor for my powerglide and being a two wire, one is an earth and one is signal
can anyone clarify if it's wired in a loop or if it's signal wire to "HI" and earth to earth
2) the VSS output is marked as pin 50 on the US wiring diagram but not mentioned on the australia wiring diagrams (speedo is via BCM as far as im aware), is this just a case of wiring and it will function as normal? (wiring to autometer speedo
thanks for any help
