aussie ls1s do not have a warning light

it all goes thru to the dash

find a usa ls1 wiring diag as they have a mil light

but then u have to retune the ls1 ecu to get the light to work

i have gone thru stuff with people i deal with and think i have figured it out

but ask your tuner first as he has to turn it on in your ecu otherwise it wont work

its not a simple just plug in a wire and go for it

i could set yr ecu up but it would cost you 300 bucks

ls1 fly by wire alternator wires go straight to ecu

u have to not connect these to ecu and find out what the wires do then connect them to i think battery and charge light in dash
