hey boxhead
Aussie ls1 ecus don't have
oil light out or ecu light and therefore
no wiring for them
the USA ones do so u need to mod the tune to get them to work
Id have to check my diags but even USA ones might not have
oil light wire as a lot of these signals are serial data
and if yr using ls3 ecu I think the Aussie ones don't have ecu light either
so u have to add wire
like boxhead said don't run pump off a switch as its illegal
and very dangerous and heaps of people do it so I'm surprised
there ain't more serious accidents
all efi cars never run pumps all the time with ignition on
