Bought at car boot sale this morning

Search the part number online and you tell us.

The part number is just for the plug.

All this is is a 'fake' tuning box, it goes to the coolant temp sensor and just increases resistance to make the car think its always cold so run rich. 
All thats inside the box is a resistor thats had a load of potting compound thrown on top.

Not worth the plastic its made from, throw it in the bin.

Thanks for that Aperture5, I did Google the numbers and like you say there just plug and socket numbers with nothing else marked on the box, and its potted in compound ! The plug and sockets relate to temp sensors so like you say it would just have the engine running rich, time to start digging into the compound just to find a resistor !

The resistor value is floating about on the internet.

Well, if you actually want a "working" (for discussed values of "working") Fleabay resistor mod... see resistor colour codes.

Why did you buy it?

 

I think that I may know the answer, I probably would have bought it too!

Just use a multimeter

 

pin 1 to 1 should be a straight link

pin 2 to 2 should have resistance

 

or vice versa
