Welcome to the forum.

It's definitely aftermarket. Could be a performance chip - I can't think of much else you'd plug in there (except for anti rust stuff, but that's low power and shouldn't require a heat sink). Take care if it's the "No Limits" variety unless you've got an EGT gauge (unlikely, actually, because the "No Limits" chips are so cheap they wouldn't bother with a heatsink, but you should still be careful with any performance chip).

It looks like a newer version of counter act corrosion protection as in the pic.

Ok it has direct positive and negative wires to t either side of the battery and then a single black wire coming out and going to a common earth point in the engine bay.
The device has a led light on it but does not operate in any key position including when running the vehicle. Maybe it's died from the heat in the hot zone.
The only marking on the device is a black shield with lines through it. I thought it might be an electronic rust protection device but how can I tell if it's working without a led indication ? I have had the car 3 months now and it is the only thing non standard on the immaculate vehicle.
There are no part numbers or further details on the device.

Your help is appreciated,

Thanks James

I can't help you but I gotta ask. Have you got a Manx beach buggy?

The wiring you describe makes it sound like one of those rust preventer dealies.
Either that or its a bomb!!

Sounds like a "rust prevention device" from that description. Whether they actually work or not is a highly contested subject, but I'd say it is kaput if there are no lights working on it.
