no, seperate ecu for the 3 door, the 2wd saph and the 4wd saph and later escos cars

you need to match the ecu with the loom with the abs units and valve block and sensors (later cars have different plugs on the ends)

you need to have abs hubs on the front, you can't fit it without
and on the rear you need abs wishbones (and then abs rear shafts)

yes and yes but the calipers have nothing to do with the sensors, you need to fit the hubs to get the abs to work, once fitted you can fit any caliper and it will work if the system is working

pain in the arse but you would need the whole caboodle, and i mean everything, the only thing that wouldn't fit your 3 door is the front hub assembly due to the offsets and the strut sizes

the abs loom is stand alone
you only need to power it from the fuse box (ignition switched) and feed it to the warning light
it sounds as if you are planning to retro fit abs to a car, your best bet is to go out and find yourself a late spec 92 sierra with abs fitted (you can get a ghia or a gls for peanuts nowadays) and as long as the abs works you can swap everything over, no problems at all
