I've tried to insert an image on this, but don't know if it will work! There is a T-piece on one of the vacuum pipes going to the IC (i think) on the left hand side, it is bunged up at the moment, is that where you would connect a boost gauge to? There was one in the car when I bought it, but wasn't connected, if I can find it I'll connect it up, could do with a genuine reading! Cheers...

Nah, didn't work! How do you attach pics to a thread? Seems like I can only use a URL, maybe that's how you do it, soz for bein a retard! :-)

Sorry can't help with the gauge problem!

you need to tee the vacuum pipe from the boost gauge into any pipe coming from the balance bar, there are 3 on the driver side near the brake servo.
