its quite easy to install, remove the stock sensor by the oil filter, have a little bucket under it, oil will pour out for a bit, and screw in the the new line and brass nut, route the tube so its clear of anything hot, and use Teflon tape on every connection, even on the gauge connection.
if you want the stock sensor to be installed as well, just put a T in the hole where the sensor was put the tube in the bottom of the T and the stock sensor in the other open end, didn't your new gauge come with instructions? mine did.
oh and if you jack the car up on the pass side and remove the front wheel you can just reach in there to remove the stock sensor, and install the new stuff.
