Run the cable harness for the sensor through the rubber grommet in the firewall on the drivers side. The power harness has 4 wires. Red, black, blue and white. The Red is for your 12v power, black ground, blue datalink, and white is a narrowband output. Wire accordingly. You will not need to wire the blue or white wires unless you run a standalone ems. Put a switch on the ground, or contact Joe_Dezod and he can help you with a relay circuit. I spliced the power into the aux power outlet in the center console.

I was even considering making and selling the relay circuit. Almost anyone can do it but I hade a nifty way of incorperating 2 15A replaceable fuses in an event of a short.

/\/\ you should

why do you need to put a switch on ground?

Prototype_xB

/\/\ otherwise the sensor/gauge will ALWAYS be on. Plus the install guide says to wire the power wire to a 12v "Switched" 10amp source. However you can switch either side you want, +/-

right, just use a switched 12v source and you dont have to touch GND...
