What Is This Thing?

[dontfeelcold]

What do you reckon the brown thing in the red circle is? I have a feeling it's some sort of comon grounding block.

[Ben C34]

It's not a grounding block.

That's fairly obvious

It's a plug for something.

[dontfeelcold]

It's not a plug as it has no ability to plug into anything.

The knock sensor shielding wires go into it among other things.

[Ben C34]

I'm sure I have one in my s2 stagea. And pretty sure it was a plug.

It have no idea what it's for.

[Shoota_77]

Not a diagnostic port of some variety?

[r32-25t]

It's not a plug, not sure what it's actual duty is but it just sits in the loom as is

Yep that's what it is.

[Ben C34]

Yep that's what it is.

What?

So it just grounds all of the wires together? Why look like a plug?

[dontfeelcold]

It's either an afterthought or just how Nissan do things. Everything for a reason and a reason for everything.

I don't know the why but I was wrecking a written off stagea and pulled that thing apart to see what it did and it had a small busbar inside to which all the wires were connected.

It's a common ground block then. Thanks guys

[Ben C34]

Oh nissan. You so crazy.

It can go in with the special pile along with the R32 GTR front suspension and HICAS

Why? Presumably it has a purpose and isn't doing anybody any harm.

Every plug on the engine needs an earth. So instead of trying to earth each individual wire they all tie in to a common point. When I was cutting all the non essentials out of my loom it had me confused for a bit, but then I realised that all of the sensor/plug earth points tie into it.

Then there is five or six wires that run from there up next to the VCT plug that get earthed out via the intake manifold. I think there may be one individual wire that gets earthed near the ECU.

It's pretty much just a way to make life easy for Nissan and keep the size of the loom down.

I asked the same question a few years ago! Apparently that dodgy looking blue electrical tape is OEM too

Honda do it too. I found stacks in the EK race car. I would bet they're pretty common in most cars.

I was wondering about that tape. Gives the loom a "someone's had a fiddle" look about it.
