R32 power fc boost controller help

[Hudeani_r32]

Hey guys. Trying to find out where the original boost solenoid cable is on my r32. It was a hcr32 but I have put in a rb26 with a single turbo . The loom was supposed to be from a 32 GTR but I can't find the 2 pin cable anywhere on it! No signs of anything being cut off either! Only have a spare 3 pin cable coming from roughly where it should be! Any ideas as I am stumped!!

Well, only to say that aint it. The standard wiring is 2 wires to a plug plug with the terminals in a t shape.

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.

[Duncan]

He did say it has a 32 GTR loom in it...

[Hudeani_r32]

Yeah I replaced the stock GTS loom with what I was told was a R32 gtr loom so should have that t shape plug. But there is nothing there! Not even any cut ends or anything! Rather confused. 

Has anyone for a wire diagram for where it should be and what part of the harness so I can have a closer look to see if it's been removed or is missing or anything?

 This 3 pin looks like it's coming from the same place that the cable it should be does and us about the correct length but a gtr ones are 2 pin I believe... Only thing I can think of is it's not a 32gtr loom... But if it's not then what is it? And surly it wouldn't be working in my car?

The boost control cable for GTRs isn't part of the engine loom. It's part of the loom that runs on the driver's side.

Yuh, who woulda thought?

[BK]

It does end up pinning into the engine harness ecu connector, just not directly part of the engine loom.

[Duncan]

lol good point. imagine having multiple looms in a car

Hmm not good news. Although all of the cables on that side were changed also from the stock I believe.

 

[GTSBoy]

Why is it not good news? Just run some cable.

[Hudeani_r32]

Where would run it to though? Splice it into the ECU plug? 

[Duncan]

I guess we are probably getting to the real question now.

PFC does not do boost control directly. You need to buy the boost control adapter, and a solenoid, and wire the 2 together anyway.

Yes. I have the boost controller add on for it. That's what I'm trying to fit! It has the t shape plug on that plugs into where the factory boost solenoid would be but I'm missing that. That's the issue I'm having.

There's 2 pins on the factory connector for the solenoid - look em up and hook into them. You also have to run cable anyway (3 cores) for the Apexi MAP sensor which plugs into a different specific connector, so run another pair at the same time.

I know there is! What I am saying is I do not have that connector on my loom! The map sensor is already run as I have a d jetro.

There's more than one way to join 2 wires together.

Just take the plug off the Apexi loom and replace with a plug & socket from Jaycar. Other side of which you attach to the solenoid.

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.

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!
