How do you change speed sensor on 96 caravan?

On top of the transfer case behind the transmission (drivers side) you will find the speed sensor. (you will need to jack up the van and slide under on your back.. BE SURE TO CHOCK THE TIRES, SUPPORT THE VAN ON BOTH SIDES WITH JACK STANDS AND PUT A BACKUP JACK UNDER THE DRIVERS SIDE JUST IN CASE SOMETHING FAILS) there is a retaining bolt holding the sensor in (10mm) remove the bolt and pull out the sensor. there will be a small gear on it. remove the gear and slip it on the new speed sensor. the replacement sensors have a plug and harness that comes with them that is different from the one that comes on the van. You will need to cut the wires and remove the old one and wire the new plug into the harness. this is not hard and the wires are color coated the same as the stock wires on the van. (black with blue stripe, whte with orange strip and solid orange) Be sure you wire each to its match on the harness. You will need some good wire strippers, a lighter (to melt the heat shrink tubing it comes with, and some wire cutters along with a 10mm 1/4" drive socket and ratchet. there is a lot of excess wire on the new plug end so be sure you tape it all up so you don't have things hanging down that can get damaged.
