I cut and butt-connected the #13 wire (which was white/blue) and...the speedo stopped working! I also tried to T-connect two different white/violet wires with no results. After installing everything according to the instructions, all I have to show for it is some useless buttons on the steering wheel.
I'm guessing that this kit is just not compatible with my 98. At least I did'nt spend too much money on this. Now I have to drive to Florida next week without cruise.
