Update I got them working, I'm not sure if this was my problem all along but when I connected the red, orange, and black wiring to the fuse taps (red, orange) and black to the ground using the supplied connectors by defi the connector never actually pierced the jacket of the wire to make a connection. So I had to open up the connector and strip back the jacket on all the wires and it worked! I used the ground in the engine bay next to the fuse box and battery too.
Since everything is wired right now but the sensors aren't hooked up yet. Is it normal for the gauges to move up and down a little bit since they're wired up but not connected in the engine bay yet and not actually reading anything yet?
