Halloo!!
No, i got a rev counter which is the wrong one - but they are a piece of **** to fit. They have 5 wires, a + and -, one to the back of the alternator (the "W" terminal i think which counts the revs), and a + and - for the backlighting circuit. The 52mm one fits perfectly in a defender spare dial module in the dash though.
Yes, i got a wiper motor off ebay - brand new for £15 thanks to our somerset lookout crew!!! Not tested it yet cos the old one is still clicking away but it's imminent!
