    Don't even need wires if you don't mind it not lighting up. Need to put a connector in the hose just before it connects to the engine - the one that runs past the battery cover and turns right to the throttle body by the EGR. Run some silicone hose from there to the access hole behind the fusebox etc which will go to the passenger footwell behind the glovebox. Run it behind the dash and to wherever you want then. If you need 12 volts for a light, there will be wires nearby but probably just as easy to run it from the cigarette lighter wires because they're switched with the ignition.

    Mechanical has less to go wrong and tends to be more accurate, thats it. Just pick what you prefer.

    Fitted one to my DTI, it's a mechanical and works fine. I fitted a 2 bar gauge to see how much overboost was flagging a fault, quite a nice addition to the dashboard

    This is the one i got, and comes with the fittings you need to get it working on a diesel (cos there's nowhere to tap a t-piece into) http://www.ebay.co.uk/itm/Smoked-BLU...item3f1d9f4774

    This is turned off

    I tapped into the manifold top section (where the hose connects to). Took it off the car, drilled a hole through it, tapped a thread on it, and screwed in the supplied brass nipple with thread tape on to make it airtight. Ran the piping through the drivers side firewall gromet to the gauge and job done.

    I intended to fit it as a temporary measure to find out how much boost was being produced when it went into limp mode, which is why i havn't put it in a pod. I quite like it so i might mount it to the pillar instead of using the supplied holder.
