Engine wiring harness connection points and earthing points help please

[Westcoast888]

Hi
Hope you’re all well
I’m desperately hunting a wiring fault that I’m documenting on another thread

Help please Flashing coil light and EML on. Multiple codes 31391 27202 8208 8216 8217 8338

3) Possibly clogged manifold pressure sensor (G31) Captured in fault code freeze frame In blockmap data Should be close to ambient pressure - especially when engine off. This sensor has been replaced with OE item.

But I’m stuck trying to find the following so was hoping a kind soul on here with a bigger brain than me (not difficult!) could shine a light please

So

Earthing point 487 & 486. The wiring diagram states they are in ‘engine pre wiring harness’ which isn’t very clear to me

D121 connection 19 engine compartment wiring harness.

D39 connection 1 engine compartment wiring harness.

I have searched the download section and the web but come up against a wall.

Hopefully this might help others in the future too

Many thanks
Jay

I think those are internal joints in the premade harnesses, not a connector block as you might be thinking.

@mmi or @n10n ?
