Hey guys,

Just finishing off wiring my 26 into my r31. I cannot fuigure out where the plug for the Injector ballast is on the 26 loom. I know its an 8 pin, im thinking that maybe my loom might be missing it?

Im scratching my head in the shed now so any replies would be helpfull

Thanks guys

It's near the relay box and the plug for the factory boost control solenoid behind the right hand headlight. It actually mounts to the same bracket as the boost control solenoid so the plug should be near that.

Thanks heaps mate, I just spent ages trying to find out what was going on.

Is the plug apart of the body loom? or the engine loom? ive got the ballast here but nowhere to plug it into

would love to get this running tomorrow guys.

from what I understand, when putting an rb26 into a gts-t you still need to wire in the resistor ballast into the 26 loom?

I don't have a common power feed for my injectors like in the 20 loom (shown in the wiring up GTR injectors to rb20 tutorial). each injector wire seems to run separately.

Surely someone knows what im on about here

Thanks

What car is the loom out of? If it's a 32GTR then the plug is on the body loom where I pointed it out. It comes out of the relay box next to two white/blue stripe wires. And yes if your running stock GTR injectors you need the resistor.

Ballast resistor needs 1x power fed in and 6x out to each injector power wire. You will find the wiring at the end of the loom near the afm plugs.

Spot on. It is the other 8 pin plug coupled to the main 8 pin engine loom plug on the front side of the passenger strut tower. You will find one of the wires is the power feed to the injectors and the other 6 are the return from the ballast resistor. I cut the plug off the ballast resistor and add a mating plug to allow it to plug into the engine loom. This means you can mount the ballast resistor somewhere behind the passenger headlight in area which should get some air flow.

Thanks for the replies guys.

I ended up opening up the loom

Each injector has 2 wires going to it - 1 of my wires was a different colour than described in in the pin-out pdf floating around. This was throwing me out at first

The wires have silver dots stamped on them:

2 dots - signal from ecu

1 dot - power

Chopped all the 1 dot power wires and wired them into the ballast resistor, taped the unused ends up and hooked up 12+ Ign to the ballast

Fired up first time ;) huge relief.

    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • 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.
