Just bought a boost guage.
Fitting the pipe through the bulkhead to the top of the manifold was'nt a problem...

BUT...

How/where do i connect the the wires up in order for the light to work?

Been told to conncet one wire to an earth source and the other to the positive of the side light...situated under the steering column??? but which wires which in the choc block etc

I need an idiots guide!

Please help...

In my opinion, the easiest way of doing this is all at the back of the radio. If you take the radio out then you will have bags of room, its then just a matter of earthing the earth (either scotch blocking into the radios earth or earthing it to a bolt somewhere. Mine is earthed to the a pillar through an existing bolt), and then tapping into the illumination wire for the radio. On an my99 this wire is grey. You can work out which is which by using a multimeter and finding which wire goes to 12 volts when the lights are switched on. Plenty of room, no dash to take apart (and they never go back right again, honest!) and the jobs a guddun!

Hope this helps.

Back of the fag lighter.....

depends where you're fitting it: all the switchgear is illuminated too, so you can get a feed of any nearby switch. And they pop out nice and easy too ;)

depends on where you mount the guage.... if it's on the a piller or similar I'd go for the foglamp illumination circuit (purple and black wires if I remember correctly) otherwise I suppose you could go the otherway if it's on the steering wheel...

The gauge is mounted in a pod at the bottom of the drivers side pillar.
Have dismantelled the bottom of the steering column but cant figure out what wires are which in the scot lock for the lights/indicators etc.

Will need an idiots guide ithink!

Cheers for the help
