My old 3 terminal flasher unit is a big heap of rust inside so needs replacing - the daft priced DS replacement @£78 has only 2 terminals and is squareish not round, presumably that means changing the connections somehow.
I have a NOS car unit in my garage that has three terminals marked L P & X am I right in thinking I can use this one as its designed for the same wattage bulbs and is the same diameter as the original?
