Hey forum!!! As topic states I need a little help wiring the q45 throttle body to a series 2 rb25det. I already have the grey plug wired to the rb25 tps plug, but I am stumped as what to do with the wires that go to the black box on the side of the throttle body. A tutorial said to integrate into wiring but doesn't state how to. Can someone please explain to me what to do with the three wires that come out of that black sensor? Thanks.

There are two plugs on the TPS, one on the flying lead, and the other onthe TPS body.

There are two corresponding plugs on your loom. Simply plug them in. As per the tutorial you will possibly have to cut the loom to make things the right length and tidy things up a bit.

Wow you totally lost me. Let me tell you what I did. So far I have spliced the grey plug off the q45 to the brown plug off the series 2 rb25. Now I need to know what to do with the plug that comes off the black sensor of the q45.

There are a couple of threads around

This one might help

Ok do you see the picture in the link you sent. That grey wire I have wired up already, that part is fine. It is just that little black box that is on the side of the throttle body, I want to know what to do with the wires that come from there. That part I do not get is, the tutorial says to integrate the stock wires into the vq45 plug(with a pic of that black box above it). How do I do that? Can someone just say were to connect the wires of the plug that will be coming from the little black box. The grey plug is all wired up and everything is good with that.

That is the link to the tutorial I followed, just need to know what to do with the wires that come from the black sensor.

I asked the question on nico club .com, and I got a response, "you don;t need to worry about that plug. it goes to one of the big white plugs near the ecu that aren't used"

I have had mine Running with only 1 plug connected, it seem to run fine, but After 4 laps on the track, the turbo exhaust housing got way to hot and is now stuffed (warped).

Don't know if it has anything to do with how the TPS is hooked up, but that was the only thing I have changed and the car was fine before. :)

      After market rear camber arm adjustment

      By V35Newbie · Posted

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.

      Continental have consistently beaten the absolute shit out of every other performance tyre in Wet/Damp/Cold conditions and give up a little bit of time (half a second at most) in the dry. Almost like it's engineered for German conditions or something. I'd def give those a try.
