Just a quick question to save me starting another thread.......

I have a boost gauge fitted but it only has 2 wires [obviously live and earth]

I now have a new gauge that has 3 wires-

1. permanent live
2. switched live.
3. Earth

The guage is a single colour and nothing fancy so I'm not sure why it needs a permant live?? Its one of the ones thats a blank face until you turn the ignition on then it lights up.

Am I right in thinking I can join the Permanent live and the switched live together and join them both to my current switched live? would be good for me as I already have the 2 wires in the pillar from the current gauge.

I don't see why not as you have no colour to "remember"

yes, join them together the same as the purple and orange on the Auto-Gauge. The reason for this is because the instrument lights on SEAT's come on when you turn on the ignition and not just when you switch the lights on, on other cars you would probably have to connect one to a switched live from the lights and the other from the ignition.

You usually elevate the wiper and twist it until it comes off.....but its a bit late now. lol

Atleast you'll get a new window and the wipers will no longer be stuck as they'll have to take them off to fit new screen.

I'd just like to add, incase anyone's interested, that on the 4 wire Autogauge ones, where mentioned that you need to join the Orange and Purple wires together, You dont really. It depends how you want it set up. I can't remember which way round it is, but one of these wires is the face illumination for the gauge, and the other is the illumination for only the needle. In my last car i had mine wired up so that the needle illuminated with the ignition on, then the face didnt illuminate until i put the lights on. I know the dials are always illuminated on the Leons, but i just thought i'd mention incase anyone is interested.

I have installed it, joined them together and it works a treat...looks much better now it matches the rest of the dash lights to.

Altough not a wiring question, just wondering how did any of you replaced the standard tubing with a proper silicone one? Is the standard tubing up to the job or should it be replaced? In one of the other threads, it mentions the tube runs all the way into the guage so you have to run the clear tube into the silicone tube, is this so?

The standard stuff is very thin walled, thicker stuff is better for vacuum.

No, just replace the whole tube in one go throw the clear stuff away.
