Boost Gauge install: How To.

Here is the walk through for installing the New South boost gauge with the steering column mount on your B6 Passat.


First off, we want to route the line for the gauge.
We want to do this through where the wiring harness passes through the firewall.

Image



Do this by using a 6in piece of straight coat hanger, and pushing the line over the wire.
Have a friend (or yourself) take another piece of coat hanger and form a hook.
Use this hook to grab the wire, and pull it through.

It will appear between the battery box, and fuse box.
Like so..

Next step is to remove the engine cover, and gain access to the main vacuum line coming off of the intake manifold.

Its the one with the hose clamps on it. The stock clamps are pinch type. Ditch them, and replace the stock hose, with the 'no-buzz' fitting.

Remember to not put ANY pressure on the nipple itself.

Route your gauge line to the nipple and use the included vacuum line to attach the two together.





Your done here.
Re-install your engine cover, and close your hood.

Wash your hands, and grab a soda and smoke.

Now we move to the inside.


Open the storage compartment by your left knee.

Push on the two tabs to enable it to open fully, and reveal the inside of the dash.

This will allow you to route the vacuum line for the gauge up to the steering column, as well as provide better access to the back of the dimmer switch.

Take out the headlight switch (push and rotate to the ON position, then pull)
Remember to turn the switch to OFF before unplugging it.

Image


Now time to pop out the dimmer switch.

Reach back through that access, and push firmly on the back of the dimmer switch. It will pop out of the dash, and now you can unplug it.

Image





The directions say to hook the red wire to the dimmer switch, and the black to a chassis ground.

We are looking for a solid gray wire, and a brown wire with a black stripe.

Connect the red to the gray, and the black to the brown/black.

All you need to do now is route your wiring, and vacuum line up to the skirt on the steering column.
Follow the directions included in the kit for connecting the line to the gauge, and mounting the pod on the column.

Clean up, and go for a test drive. :thumbup:

I just wanted to say nice right up. I can do most of my.own mechanic work. That is if I want to. LOL. Wiring has never been my thing really and I have got to say some of the other DIY weren't right for me. They had a dif gauge with a harness. But your DIY was super basic simple and anyone can do it with this DIY. Good job man. Really nice

I have not seen the pod mounted in a B5, or B5.5, so I cant comment on fitment.

ECS Tuning is where I got my kit, and from what I have found, they are the best price on it, and have it on hand more often.

I paid around $200 USD after shipping and taxes.

Hope you go for it, it is a nice addition, post up pics if you go along with the install.

I know I did this writeup for a B6, but if any of it helps...

Thanks, I am a first time DIYer looking for the first time to maintain and upgrade my 99 Passat 1.8T wagon.

Ultimately I am looking to chip the ECU and replace the turbo with a K04 but probably another K03. But as both are stock at the moment and I get to know the vehicle a little better, I have heard that an oil pressure gauge is also a useful gauge to have.

So if you could only have one, which would you install oil pressure or turbo boost?

While I am pretty handy, I am new to DIY vehicle maintenance and upgrades so don't to attempt anything beyond my means and can't see any easy way to mount two gauges. Is there? Maybe a column and A pillar mount?

PS Happy to take pics if to either. Would I post here or start another thread?

I would actually run both.

Start with the boost first, unless you have issues with your oil system.

Deciding if one is more important than the other, will have to be your call.

Since you have a B5 style car, you have a few more mounting options than I do.
I would stay away from A pillar pods, unless you do not have pillar air-bags.

There are also mounts that replace one of your A/C vents.

When you do get it installed, and you want to put up pics, you can start your own thread in the proper forum, or put them here, either way works.

I can't say if I have any oil issues except that the car seem to be running fine if only as it would after 160,000. After relying on dealers and mechanics I hoping to give it the TLC and upgrades from now on.

As far as I know a 99 B5 doesn't have A Pillar bags but I'd prefer the look of gauges in the air vents but also because I have a power cable tucked into the A pillar which I can remove and connect when needed to my GPS mounted to the windscreen in that corner. I have only seen one picture (below from this POTM)

But I would have thought this was a completely customised job. If not, where can you find an air vent mount? The options in auto stores seem pretty limited or non existent especially for a VW here in Australia.

Which is the proper forum? Showroom? Thanks
