Scoobs_19998

So I have a uk2000 1998, I was running some power wires to the boot under the floor for some leds and I thought I'd check out the ecu, I found a little black box tapped into the far right plug. I've checked out the pinout for the ecu apparently its tapped into the control system ground, o2 sensor shield and is joined straight onto the yellow and black wire coming out of the wiring loom. I believe that they're the only wires by the looks of it. The box itself has no information on it whatsoever only a little opening to a little blue chip on the board.
Does anyone have any clue what it is ?

As far as I can tell the Yellow/black wire goes to the boost sensor
