This is how you wire it up:

Brown is chasis ground, (terminal 1 of connector x13441).
This goes to the chassis of your vehicle.

Red goes to fuse fl4, (terminal 2 of connector x13441).
This goes to a 100 amp fuse.

Green/white goes to fuse f39, (terminal 1 of connector x6975). This goes to an ignition fed fuse rated at 15 amps.

Yellow goes to alternator circuit, (terminal 2 of connector x6975 It splices with the black/yellow off of terminal 1 at the alternator. This one must splice into you alternator as described above.
Violet/white is the data line. It is terminal 3 of connector x6975. You can leave this one out.
