Rb25 Coilpack Loom

[iruvyouskyrine]

Hi all,

Just putting the loom into my RB25 Neo and I can't find where either my coilpack loom or knock sensor loom plug into the main harness.

On the main harness there is a single 8 pin plug that sits just behind the intake plenum and both the coilpack loom and the knock sensor loom plug into, meaning I can only have one and not the other

Worth noting the car is an R32 and I sent my RB20 and 25 loom sent off to get spliced together so I'm not sure if the guy who did that left a plug out or I'm just going crazy and missing something obvious?

I don't have access to any RB25 S2's (ie no igniter) to have a look at otherwise I would.

This is the plug with the coilpack loom plugged into it

And this is the only other 8 pin plug on the loom except the one for the injectors.

I have been using the R34 ECU Pinout in the service manual and I know the knock sensor loom uses pins 60,62 and 63 and the coilpack loom uses 1,2,3,7,8 and 9

As you can see in the first pic the wire colours seem to match with the coilpack loom and not the knock sensor, so I guess it has to be my knock sensor plug that is missing?

Any help is useful as I'm very keen to get my car running as its been off the road for 8 months now and it's the last thing stopping me from getting it running!

tl;dr

Where does the RB25 S2/NEO knock sensor loom plug into on the main wiring harness?

There are 2 similar plugs off the top of my head. One is for coils, the other is for injectors.

Not to sure if that helps though

My injector plug is at the front of my plenum and is a grey/white 8 pin connector. I will busy out the multi-meter and test for continuity at the pins for coilpacks and knock sensors and see where that leaves me.

Completely useless probably, but there are some loom plugs at the front of R33's near the fuse box (think they are around the std washer bottle, but mine is gone so not sure, my plugs are on a bracket near the fuse box). There are a few plugs on there anyway, I know one of them is for the rear lights, not sure what the rest are. Not to sure as you have an R32 Chassis and an R34 engine so everything that I dont have lol
