Yea, if you undo the 4 screws (1 in each corner) of the lower half the dash board, drivers side under steering then you'll find hundreds of wires.
Use a multi meter or test light to find what your looking for

Earthing point on A pillar behind kick panel I think

Do you not have fitting instructions for it! You should have a gauge and sensor to fit into your exhaust!!
