I just put my n5 in my 1999 ford escort LX. Everything works great accept the speed pulse sensor doesn't pick up. I've checked around on the12volt.com and on rostra.com. 12volt says its a black and grey wire but rostra says its a white and black. When I installed it the system I was looking at the PCM and found a black wire that said VSS- F2 and plugged it into that(didn't work). so I'm kinda at a point where I really don't know what to do. Does my car even have a VSS wire? I know they are used with cruise control but I don't have it. Any insight on my situation is appreciated.

Try going to The12volt.com for your answer, it helped me.

Just realized that I posted in wrong section, sorry!
