Another wiring question

[booomer]

Hi guys i have searched the wiring stickys to no avail.

I am re-connecting my engine loom (m50b25 non vanos - from e34) and i have three connector plugs left.

one is a two pin connector that has two brown wires going to it and when i used a multi meter to probe the ecu pins, it did not appear to be connected to any of them

The second is a single pin connector that has a single brown/green wire going to it. When i probed the ecu pins for continuity it appeared to be connected to pins 6, 23, 24, 25, 26, 28, 34, 50, 51, 52, 55, 56, 87 and 88. i assume from this that it is some sort of earth but i can't work out for what!

The third connector does not come from the actual engine loom but from the fuse box. it has two wires going to it one brown and the other red/white.

Any help with finding which ones go where would be great

Cheers

Any chance of a pic, I pulled my E34 loom apart a few weeks ago, so could tell you whats what from their position on the loom.

The only single pin connector I can think of is for the oil pressure switch (behind the fliter housing on the engine)
