Great looking car mate, sounds the b******s.....
I had a bit of a problem fitting my gauges, to be honest. The silicone tubing i had i routed through the bonnet release grommet and ran it along the wing with the cable and then across to the FPR.
Trying to get the tubing through can be a headache as the silicone is 'sticky'. Dont do what i did and lube it, made it worse

I used a stiff wire to poke it through and took the dash away below the steering wheel and just stook my hand up there and felt for it. Might make it easier if there is 2 people though..
I used this thread for the installation, mate.

I works a treat. Just to let you know though, even with a permanant live the Autogauges can still 'lose' there memory, but not all the time. You may find that you have to change to red sometimes as the first default colour is blue.
Just a thought aswell, sorry to go on

, but if in the future you want an Autogauge oil temp gauge then you might want to route some thin green wire through at the same time as the tubing as this can then connect to the temp sender unit on top of the oil filter housing. It would be a mare to do afterwards.
Cheers.
Neil.
