Routing ?....Sorry lukedog..didn't see your request.. I ran the U Gauge Cable left out of the OBD plug and tucked it under the edge of the 'rubber' inner driver's door seal up to the dash level. (A little lube on the cable helps it slip behind the door seal) ...and from there across the dash area to the mounting area. I chose the windshield mounting bracket. It offered flexibility and good viewing. I secured the bracket as close to the lower left corner of the windshield as possible. I left enough slack in the gauge cable for the gauge to be easily removed and replaced. (i.e. to be reconfigured or stored it out of sight) Works great! I'll send pictures if they'll help. hope this helps... Rob
