OK, you can all laugh, but I'm trying to fit a boost gauge in one of the DIN slots (along with 2 other gauges) and I've now spent half an hour trying to figure out where to feed the vacuum hose thru the bulkhead! Anyone?... please help.... maybe its the sun!


And another thing, Where is my ECU, I need to get its part and serial number?

Thanks

The ECU is found underneath the plastic panel between the windcreen and the back of the engine bay. It is parallel to the windscreen and it is really easy to remove.

As far as the other question goes I'm sorry I haven't a clue

Further clarification- the ECU is on the passenger side.

Assuming it's your Aero that you're trying to fit a boost gauge to, the easiest thing is to tee in to the existing boost gauge line.

Andy, I meant tee it in to the vac hose in the passenger cabin that leads to the instrument cluster boost gauge. You'll get easy access to this by taking the top of the dash off.

OK, but stay with me on this one!
I still need to find a point at which i can feed wires thru the bulkhead as I wish to fit a water temp gauge and an oil pressure gauge too! Or do I start drilling holes

Hi Andy,
You'll find a very large rubber bung in the firewall behind the glovebox. Get in the passenger footwell and remove the felt above the passengers knees and it's possible to get at this bung.

It's a T30(I think, if not a T25), and it screws upwards from a hole in the instrument cluster recess, about 3" from the left edge and 1½" from the front.

Other screws to remove it are behind the glovebox and at either end, 2 under each speaker grille. The drivers side has a 5mm donut packing ring- be careful this doesn't take a jump down inside the guts behind the steering wheel


Once you have removed the screws, you then have to battle with releasing the steel cable that runs between the bottom of the two A pillars and is clipped to the underside of the dash in three places.

Are you talking about the one thats just infront of all the rev counter/speedo/fuel gauges etc.

You can only really see it by getting down low amongst the steering wheel and looking up?.

Hope that helps?.

and thats what I did..........eventually!

Idles at -0.7 bar, base boost seems to be 0.5 bar with max boost 1.2 bar in 4th at 3600rpm (its fitted with a mbc), does that seem healthy?

Thanks for your help
