I got a tach the other day, and I have been trying for like the last 2 days to find the wire that has the RPM reading in it. I looked at wiring diragram and still cant find the damn thing. If anyone knows where to get the RPM reading from for a 94 escort lx please tell me, I am getting annoyed.I know I can get it from the old tach, but I dont wanna remove my dash. Big pain. I know there has to be a wire under hood that has it in it. Anyways, please lemme know soon, I spent 150$ on this thing and it dont even work, lol.
