What on earth ?!?!?

[Lee S]

Was just having a poke around the engine bay on my car and decided to remove the scuttle trim to have a quick check and make sure the leaves hadn't filled it up completely when I noticed this thing...

Doesn't really look OEM and looks like it has been added afterwards. Stuck to the top of the ECU with sticky foam or Velcro and a cable/s going off down into a grommet that looks like it has been pierced and then some kind of silicon or mastic added. Looks like a GPS tag or sensor or something.

So questions....

a) any idea whet the hell it is?
b) is it OEM or something aftermarket?

Had the car remapped at MRC and they never mentioned anything but I noticed they had the same scuttle trim off to plug into the ECU I guess.

Are there any ELSA diagrams that show this thing??
