Got that in my Cossie - superb little gauge and accurate too and fit perfectly where the dashboard light dimmer used to be (had to file 2mm out of the hole and cut the little fins off the gauge case) - I'll get a pic if you want?

Although I didn't fit the sensor as he describes in the instructions, I modified a BSP tail fitting to house the sensor in allowing the probe to protrude about 5mm into the plenumn. To do this I filled the BSP fitting with Sikaflex and then pulled the probe through it wire first and then crimped the tail fitting to secure the wire to stop the probe being blown out or sucked in under boost/vacume - The sikaflex cured to creare a perfect air-tight seal and a nice finish with the sensor now being easily removed with a 12mm spanner
