I was looking over the schematics for the message center switch and they are wired directly to the instrument cluster except for one wire that goes to the SJB for illumination. If you are the hack/mod type you should be able to make your own harness. Another option is to go to a bone yard and get the harness. I've had one person so far try this with success. You do have to splice into the ground wire and according to the schematic there is a splice point at S201 or you could tie into another ground. I already have mycolor so I didn't have to do this mod but thought there might be others who want to do this mod.
