I pulled out my passenger seat to put in a GTR seat I just bought, and saw this box kinda thing coming out of the carpet with a plug that must have been plugged into something once. Does anyone have any idea what it is? I am very curious

post-63044-1253066669_thumb.jpg

not sure have a similar thing in my r33 s1, not sure whats it's for. I had a bit of a poke around with the multimeter with the interior light on, then the doors open, and with engine running and i couldn't detect any current.

I've got a SII Gtst and it has both drivers and passenger seat belt warning light harness, plus a cat temp sensor, so could be either, but I'd say seat belt. Logic tells me a cat temp sensor wire would be too bloody hot to go anywhere near flamable materials for at least a metre or so until it cools enough.

If it's the same as a R33 it's the plug for the cat temp sensor. The drivers side has the plug for the seatbelt.
If the car is a GTR, cat temp sensor, non-GTR who knows, most likely the seatbelt (I'm fairly sure only the GTRs have cat temp sensors?)

+1, cat temp sensor.

you can see that it has a stainless braid outside which is required for the heat resistance

nothing...unless its plugged in :D

it warns of high temp in the cat - ie cat blocked.

Yeah but where is the wire it plugs into!! Mine is the same as Pic with the tail but No connection to connect it into!!

Oh and what is that vent thing???? Been wondering about that to!

I checked after someone mentioned it was for the seatbelt and sure enough there is the other half of the plug coming from both the GTR seat and the GTS-t seat i pulled out, but I havent plugged it in yet. I might try tomorrow and see what happens.

Well I plugged it in and nothing happened, how anti-climatic. Kinda seems pointless. I also saw the cat sensor wire with the braided line nearby people were talking about.

I have no idea what it is but ill tell ya a funny trick

If ya fit airhorns under your passenger seat and wire it up to your glovebox

Then when casually cruising along with a friend oneday you ask them to get something out of the glovebox...

Absolutely priceless

    • Thanks Duncan! Yeah it's street use for me only. Maybe occasional track day. Any difference in noise when running with the two pumps? I would expect the lift pump to be more quiet than the main pump so hopefully not? And yes, unfortunately quite a big price difference to the simple hanger setup. Though I'm usually willing to trade money for better reliability and future-proofing. Buy once, cry once and all that. I'd be very happy to never have to deal with fuel pump / wiring issues again  
    • The old manifold was quite under the GTR strut brace.  The new manifold is quite [unknown] the GTR strut brace. The GTR strut brace was needed to clear the bonnet vents. The Old strut brace will almost certainly clear the new manifold, but not the bonnet vents. The old strut brace will almost certainly clear the new manifold, and the new bonnet without vents. But I am hoping the GTR strut brace clears the new manifold :p
    • On the bright side, at least you knew that it happened and remedied before anything happened. A friend of mine just took his Fiat 124 to a shop for an oil change and they didn't tighten the oil filter housing properly. 4.5 quarts spewed out and even after refilling + tightening the cap the engine has a tick now.
    • So, more pain. The FAST manifold is a little larger than the stocker. This is problematic because there really wasn't much clearance to begin with, so going from 'barely enough' well into 'no' is sad based on the external dimensions of the thing, even though where it bolts to the head is the same. Result is the fuel rails sit a good 25mm higher, and this is a bit of an issue with the wiring that runs behind the motor, and the fuel lines, and everything else. When pushing the manifold on, it required a huge amount of force to crush wiring looms to fit it, sensors like the MAP sensor are about 1mm from the firewall, and the FPR just has to bend ABS lines to be forced into place. After some brainstorming and some sad drinking, the loom for some reason ran from the grommet behind the ABS sensor, then to the driver side head, then back to the passenger side head. So all of this was pulled back and stripped, a few wires cut and rejoined, so that the 'branch' was now on the passenger side's head as below: Before you basically couldn't see anything behind the driver head. This is much improved! The MAP sensor is now pointing up (instead of at the firewall) Brackets have been made up for the rail. The rails are for a LS1, the manifold is designed around a LS2 as it's base. Which of course has slightly different bracketry and water pump clearance, hence the mods people need to do. Should be hopefully mounted tonight. I spent money on a new FPR that is slightly more compact than my Turbosmart FPR1200. The gauge has also been moved to the rail. There's also apparently an ORB to AN Union instead of the adapter, because the ~25mm of the current adapter is going to make the difference. Provided this all goes together and arrives today, it'll be the totally not stressful attempt to start it.
