No, you have to run a separate MAP sensor on Power FC purely for the boost control side mate, the boost control does not use the engine load MAPs which are tapped into the 2 X AFM signal wires. So on a GTR d Jetro you end up having three Apexi MAP sensors on an RB26.

Where can you plug that into though? As the plug for it on the ECU is already used with the other map sensor.. and I am running a hks t51r single .

I don't have any 2 pin wire there to do that! That's the problem. The gts doesn't have the same boost solenoid as the gtr. Has one over by the turbo. But as that loom as been changed for the gtr along with the battery connector loom I don't have that either. All there is is that 3 pin cable where the correct 2 pin should be!

Why is this so hard?

Run a new 2 core cable from the ECU adapter out to the engine bay and put a matching plug and socket onto it and the boost solenoid. You know, manually, like with your hands. A little actual wiring, not just plugging shit together.

Would rather not have to cut up the ECU harness that's why. Would rather of used the factory wires if they were there. But as they are not I'm asking for help on other options. Would rather replace my broken stand alone boost controller than hack up the harness lol. Only went for the Apexi as I thought the garage had fitted the whole gtr loom as I supplied them with it including the fuse box side of things. But looks like they haven't. Even though the battery cables have been changed for the new ones.. that's why I was confused in not seeing the factory 2 pin for the solenoid.

to be honest, I think you are best getting someone to do the install for you. The process is reasonably straightforward but I guess you aren't confident to do it so best get some help rather than get it wrong and blow your motor up

The connection from the PFC to the solenoid is 2 wires, but it is not plug an play. Any auto electrical person should be able to look after that part.

You also need a pre throttle boost source for the map sensor, which needs 3 wires back to the ECU too.

I'm more than confident in doing the work. Done most of the work on the car myself. And the kit is plug and play if I had the stock wire as it has the same plug. Even if it wasn't the same plug I can happily change them to ones that match. The problem is I don't have that wire to do so. And would rather not cut up a perfectly good harness after having problems with a hacked up one from its life in Japan! What I want to know is exactly where on the loom the cable for the gtr stock boost solenoid is. And if I can in even fit the gtr loom from the fuse box side into my gtst and it work. Everyone seems to be ignoring the questions I have asked! I know where it should be fitted And how to fit it. But I don't have that option so need advice on what else I can do.

It's not on the engine loom. It's on the driver's side engine bay body loom. You don't have it. The wires are not there. Stop looking for them and start plumbing in the cable that you are going to need.

Plus, you're not having up any ECU loom. You're just going to stitch 2 wires into the PFC boost controller.

This is wrong. Because, as I posted MUCH earlier

There is no "standard boost controller cable" on an R32 GTSt. They didn't have a boost control solenoid, so......they didn't have a cable for it.

The Apexi solenoid basically needs 12v to one side of the solenoid (usually powered from IGN pin 45) and then switches to ground at the ecu at pin 25 for the pulsing of the solenoid to bleed air.

      Mistakes were made, my R34 Story

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
