33gtsts2 Cable Through Firewall, Where?

[Torques]

Hello there,

I need to run a cable from my boost controller (driver side) into the engine bay.

What's the best location for routing the cable through the firewall?

There must be some existing cable ducts that I could use ... right?

Thanks for any hints ...

For my boost gauge I ran it through the existing grommet into the drivers wheel arch and from there poked a straightened coathanger through one of the rubber grommets under the dash. Took a little bit of fiddling but got there in the end

yeah what he said. or you could drill a hole the size of the hose. but i would just go through an existing grommet

I rather not drill and will check out the existing grommets ..

For some reason the previous owner of my car decided to not use the gromment, but instead feed the boost gauge line between the grommet and the metal. Works fine.

Actually, it's a bit easier to do too... I did the same when I installed the light in my pod cover.... ran the power wire between the grommet and metal on the passenger side, seemed to be more room and more give for me to fiddle with.

Hi ...

Hmmmm

Between the grommet and the metal ..

Doesn't that cut into the wire over time?

The cable I have to run into the engine bay has a connector about the diameter of an index finger ...

So I guess I need a bit of space ..

But no worries, I'll figure something out I guess.

You'll end up with a wet floor, if the big grommet under the inner gaurd isn't seated properly every time it rains you'll get a leak unless you use heaps of silastic as well

PS in english does cable = hose or electric wire? just trying to convert to colony speak............lol

[mosquitocoils]

Nah, no leaks... the one on the passenger side goes directly from engine bay into passenger footwell... not sure about the driver's side one though, never looked.

Mosquitocoils,

Does your 33 have ABS? I remember looking at some of the DIY threads when i was doing my boost gauge and they were saying to go through on the passenger side... the only place i could find that even looked remotely like i could pass a wire through was behind the ABS controkller... so i went for the drivers side option

[tridentt150v]

drivers side is much easier to use anyway, its short ah=nd direct, I've got all my stuff throught there, boost hose, 3 x gauges, WMI, WMI solenoid, and probably stuff I've forgotten.

I was surprised when I heard the term PS in an English tuning video.

PS has long been abolished as a power figure in Germany ... all the numbers are in KW these days.

PS

This unit (German: Pferdestärke = horse strength) is no longer a statutory unit, but is still commonly used in Europe, South America and Japan, especially by the automotive and motorcycle industry. It was adopted throughout continental Europe with designations equivalent to the English horsepower, but mathematically different from the British unit. It is defined by the Physikalisch-Technische Bundesanstalt (PTB)[7] in Braunschweig as exactly:

1 PS = 75 kilopond-meters per second

(75 kp·m/s)×(9.80665 N/kp) = 735.49875 N·m/s ≈ 735.5 N·m/s ≈ 735.5 W ≈ 0.7355 kW ≈ 0.98632 hp (SAE)

The PS was adopted by the Deutsches Institut für Normung (DIN) and then by the automotive industry throughout most of Europe, under varying names. In 1992, the PS was rendered obsolete by EEC directives, when it was replaced by the kilowatt as the official power measuring unit. It is still in use for commercial and advertising purposes, as many customers are not familiar with the use of kilowatts for engines.

Thanks for that, I'll remember for future use, Torques = BS not PS

wow, that went way off topic, LOL. being from the wasteland, i'm impressed at how random that post was.

Thanks for pointing this out ... you have a valid point there!

Cheers for that

Hello there ...

I just wanted to report on my progress.

After searching for a location with enough space to route my cable through I gave up since there was no such thing in my Skyline ...

However after some searching I was quite lucky and found a spot were there was a mark for a hole but without it actually being cut out ..

After some drilling and work the hole was to my satisfaction ..

(here it is already coated with rust primer)

In the meantime I have searched a local auto-yard and secured some grommets, one of these will be a perfect fit:

Here's the location of the new hole:

Good Andrew!

Quite a Grommet Collection there!

R U sure one of those isn't a diaphragm?

Coming back to a northern winter eh?

1st Anniversary of your 'Line too!

[Torques]

Hey Terry,

No ... they're all grommets (I must know since I scavenged them myself) ..

They're mostly from German cars like VW and BMW.

And yes ... I thought I might start collecting those

HaHaHa ..

No ... I thought I better get some more (just in case).

You are correct It's been almost a year since I bought my Skyline.

Thanks for remembering!

These days the car sits mostly in it's own garage.

But I'm busy installing the electronic boost controller (that's why I needed drilling this hole

And yes ... Winter is looming

Cheers ...

Andrew

Hello there ..

I just wanted to report that after some work I got my EVC installed alright.

(the hole in the firewall was for the control cable for my EVC / BoostController)

I have never done this before but didn't want to mount the solenoid at the firewall.

Here's what I came up with:

I made an adapter from 3mm aluminum

The adapter connects to the boost solenoid:

The whole thing was mounted using one of the airbox bolts:

And here's where I mounted the EVC-Unit inside

(It's not perfect but I wanted to have easy access to the controls of the EVC)

All what's left now is testing the whole thing which I couldn't due to bad weather ..
