Im looking to make an LML bench harness...im looking at the schematics, but wondering if anyone else could check my work.
I saw EFI Connection's LML standalone harness, but it looks like theirs only uses 2 of the 3 connectors. In looking at the schematic, it seems like the LML harness requires all 3 connectors? Or does it? Obviously if one of the connectors has an internally bonded circuit, I would rather just leave off the 3rd connector to make the bench harness less clunky.
C1, pin 48....ignition +12v
C1, pin 73....ignition +12v
C1, pin 26....ignition +12v
C1, pin 67....battery +12v
C1, pin 46....GMLAN -
C1, pin 66....GMLAN +
C2, pin 17....ground
C2, pin 18....ground
C2, pin 21....ground
C2, pin 73....ground
C3, pin 73....ground
This is EFI Connection's harness...clearly only shows 2 connectors, I cant see which two though.
thanks
Ben
