boost Gauge installation

[senilykSkylines]

yep thats what i was referring to. there should be a screw at the back next to accelerator and 2-3 clips next to the driver side door - after you've undone the screw, a little bit of force and the panel should just pop out (be careful though).

you should see a fair few wires etc, gently push them to one side and look upwards towards the right - there should be a hole there. Obviously best to do it in the day light. If you cant see it, pop your bonnet - look at left strut tower - behind that there should be a black box (factory boost sensor) below that is where the hole should be (from memory)

ill take a pic if you want.

Thanks mate. I think I get ya. I'll have a go next time I have day light and time after work. If I am still lost I'll ask for a pic!

no worries - give me an hour and ill post a pic of my setup (at work at the moment)

the pipe below is where i spliced a small section out (no more than 5mm) i put the T piece in, connected the spliced pipe to either end of the T piece, attached piping from the last hole on the T piece which on my boost gauge (2nd pic) will connect to the new boost gauge sensor.

pic of the boost gauge (autogauge from just jap for those playing at home)

pic below is a mock setup of the boost gauge - im guessing most gauges these days come with the small circular filter (top right in the pic below) I cut the tube going from the black boost sensor to the T piece about half way - attached the filter (helps to smooth out the movement of the needle on the boost gauge / stops dirt/crap flowing back into the boost sensor)

lastly, pic of the location of the hole i used to run the tubing / wiring in under the drivers side kick panel then up through the steering wheel / under the dash etc ready to be wired up to the cig lighter / ignition etc.

Ok, intensely frustrating. I took the kick board off and tried to feed the line through down there... no sign of it. So I took a box off with the letter "J" and looked behind it and it seems like an inclosed panel with a wall where my line should be coming through.

Hmmm. Is the reason that I cannot find it because I am using a bendy/curly bit of pipe that came with the gauge? It may not be reaching down there.

Am I looking in the right place?

cheers,

Dan

P.S. Thanks for the photos! Though I think the connecting the T bit seems the easy part.

Hey defari,

Looks like we lost those last few posts! I am still keen for that pic. As I said in the wiped post, the furtherest I got was getting it into the side panel behind the wheel. I am guessing this is not the route because I could find no way through to the foot-bay area.

thank you for your time!

the grommet you can use is one the right hand side of the accelerator pedal and the bonnet release cable goes through it, just peel back the sound deadener and then put it back once the line is fed, then in the engine bay use some pointy nose pliers to grab it. the hole is pretty much in between the firewall and the drivers side tower, oval shape hole.

another thing i reckon looks good if you mount your gauge up on the dash is running the vac/boost line through the dash via a small hole. ill post a photo tomorrow, looks pretty neat and you can do the same with oil pressure gauge.

FINALLY! After much toil and suffering, it is done!

I sent it up through the bonnet release catch's grommet and managed to find it and pull it through to the engine bay. For others who try to do it this way... the grommet that the bonnet catch runs through must have a sock-like thing that the cable runs through after the grommet. I tried for ages to push the vac/boost line through but it always only made it a couple of cm and wouldn't go any further. I pushed a number 8 wire up there in the end and poked a hole through the sock and then sent the vac/boost line up through that hole (I had to push and feel for it). I hope there isn't anything wrong with doing it like that...

Glad that nightmare is over for such an apparently simple process.

I thought this was going to be easier than it has turned out. I just can't get my fingers (or pliers) down to grab the wire I stuck through from the cabin. Attached image shows where I'm looking. I just can't get it. Is there a way to find it from in the wheel well and poke it up? I had envisaged it just being a grommet on a clear spot of the firewall but noooo.

lastly, pic of the location of the hole i used to run the tubing / wiring in under the drivers side kick panel then up through the steering wheel / under the dash etc ready to be wired up to the cig lighter / ignition etc.

Old thread, but I'm hoping people are still using this valuable information - I did my Autotechinca boost gauge today for the first time as a bit of a trial and could not have done it without this information - take a bow sir.

p.s took me all f$@&ing day haha

Thanks!
