I purchased this set along with their GPS kit, but they do have a manual sensor type version as well. The universal unit as I remember runs everything off of 12 wires. I did purchase after market male and female connectors so I could unplug the unit. On the car side of my wiring harness I cut and soldered 2 penny nails to the wires and simply plugged them into the factory harness and taped around them to hold them in place. I chose the White color option on the gauges.
