I relatively new to this forum so I don't know if the topic has been discussed at length. Could someone provide info on where the best passthrough points are thru the Firewall ? If so, what tools are best used to get through. I'm installing 2 gauges/boost controller/turbo timer.

Thanks in advance to those that can help ! :yesnod:

I am at work and can't get you pictures, but there is a way to go out on both sides of the car at the door.

I passed the wire for door lock button out through the boot where other wires go out for the doors, you should be able to pass your wires out the same way.

If you open the hood and look down on the driver's side with the door closed you should see a bundle of wires going into an "L" shaped plastic covering. Follow these wires back and they form a drip loop and then are wrapped in black tape to a rubber boot. Both ends (outside and under the dash) are wrapped in black tape. (This was fun to get at under the dash...my wife came out and wondered why she could only see my feet on the headrest.)

Thanks GO_DRVN !

I'll take a look tonight.....that must have been a tight fit under that dash buddy ! :)

Do you think there will be enough room to pass all that plumbing ? Rubber hose and wiring ? Hope so.

Cheers,

Look for the foil.

When I ran the temp probe for my mirror I found a place on the drivers side. The hole is covered with a piece of foil backed tape. There is a rubber plug under it that you can know out. Depending on how big the leads are you should be able to snake your wires through there.

As long as you aren't trying to pass a garden hose you should be OK.

You will definatley need some type of light and probably only use one hand for most of what you can do under the dash, it is a tight fit. Fitting cable ties is a lot of fun with one hand as well as trying to re-wrap the tape.

The panel under the dash has plastic push-pins and velcro to hold it in place, not too difficult to remove. I used a putty knife and had no problem with the pins.

I also pulled the plastic "L" off the car to run my wire, but you shouldn't need to do that. If you had to pass hose through there you would have more trouble since it is a tight, flat fit.

That is exactly where I ran the plumbing for my boost controller and wide band O2 sensor.
Very easy and plenty of hole diameter.

I went through on the driver side, behind the ECM where there is existing wiring going through a hole that has a rubber boot on it. I cut a notch in the rubber boot and I have two air tubes and wiring going in.

Here's a couple of pics showing where I ran mine.

You can see the bundle of wires and hoses coming through the firewall (just above the washer fluid cap).


Here's a pic showing where they go through under the dash.
I had to cut a small notch out of the fiber that covers the hole just next to the dead pedal.

The hole is already there.
It is covered with a small ~4"x5" piece of metal foil that is adhesive backed, just pull off the foil.
There is a plastic plug in the hole that you just push out - it's very easy, took all of about 5 minutes.
I did cut out the middle of the plastic plug and re-inserted it as a grommet.

Gosh, sorry - I can't help you on that one...
My gauges are all LED and dimmed via a photocell, when I wired them all I needed was an ignition switched 'hot' wire from the accessory fuse box.
