Speed sensor on a 98 Honda CIvic?

In a manual transmission model, walk over to the passenger side of the vehicle lean over under the hood of coarse and look straight down to the left of your fuel injectors. It is a three prong plug that connects to a small housing on top of the transmission. If you have an aftermarket air intake it is easier to see. There is nothing else around it for about 1 foot so you should spot it right away.
