That should have a control harness and an output harness. the control harness should be. IIRC it is a ground side flasher.
Input
black - ground
red/white stripe - 12v +
blue control - 12v+
green control - 12v+
white/violet - scan lock 12v+
purple - low power 12v+
Output
1 yellow + white/yellow stripe -
2 orange + white/orange stripe -
3 red + white/red stripe -
4 brown + white/brown stripe -
I have used these in the past to flash both the lin8's and the lin6's.
