It rehashes itself, so dont get confused.
Cut #7 on X20 Main harness - Mine was Lime Green
Cut #8 on X20 Main harnees, attach to #1 on the X6031 harness - Forgot what color that was on my car, but it attaches to the Grey wire on the smaller connector.
Next steps are just for the X6031 Smaller Harness.
Wire #14, White and Black stripe must be connected to the Blue clipped harness behind the instrument cluster. All i did was run a wire from #2 wire on the Blue connector, for the cluster, to #14 on the X6031 harness. Not sure if i actually cut the line at #14, or just spliced it...im sure i cut and wired it to it.
Other than that, there are no other mods to the harness that i know of.
