Picked up a wideband gauge and sensor at a discount and I'm looking to wire it up. Other than having the bung welded on to hold the sensor by a mechanic, how much of a pain is it for me to wire the sensor up to the gauge? Is it just a matter of snaking the wiring up through the firewall and into the a pillar to the gauge and then getting power to the gauge?

 

Yep. Power, ground and plug in the sensor. Google how to do a free air calibration for your brand of gauge.
