Just to add I wasn't randomly buying sensors, all of the ones I bought were listed as being compatible. c***s. Also, the rubber on the new ones has started to perish, not a problem but the quality doesn't seem a patch on the original ATE ones which you likely just can't get anymore.Fronts same, rears ones male ones female.
Make sure you buy the right ones. I bought 4 before I finally got the right parts, f**king abs sensors galore round here.
Have a look under the car at the connector and and maked a note of what the gender is for each side (I foget if they are the same or not).
