The Boost gauge came with small diameter boost tubing and a T piece to plumb into you boost point, I used the top of the diverter valve. The oil temp gauge came with a temp sender which is the correct size for the
Ibiza.
Both gauges came with backlighting bulbs, but I bought some red leds and fitted them to mine instead. The photos don't do the dials justice as in the daytime the needles are orange not red as shown, the night time photos make dials look hard to read but this is again just the photo.
You will need to supply your own wire and spade connectors though.
I took all my electricity supplies from the back of the headlight switch, but you could use the illumination from the ashtray. You will need an inline fuse holder and fuse for the oil temp gauge. Fitting the oil temp sender is very awkward, very difficult to get to and not much room to manoeuvre.
I did cut the bottom of the cubby hole out, as when the boost pipes and wires were fitted the bottom of the cubby hole prevented the gauges from seating properly. I found this out just as I thought I had finished, so was starting to lose patience. I don't intend to remove the gauges before selling the car so don't see it as a
problem.
Some makes of gauge are shorter though, if you don't want to butcher your cubby hole.
