the wire its the colors you described. If you can't find it in the engine, its because its no there, its in the transmission. Its all the way in the back, before the driveshaft. Its rounded and has two cables going out. If you find it follow the wires up and see where they were cut, and so on. If you spedo works in your car, then you can jack the signal from it to your ECU. The cable that goes to the sensor comes from a harness that comes out of the right side of the car, looking at it from the back. Its right next to the battery. there's the engine harness and there's the transmission harness. from there you should see the cables that go down. they clip to the body of the car and separate underneath the fuel filter. the one for the speedo breaks away here, and goes out by itself. Its wraped in a black tubing. you should be able to find the color wires on the top of the harness right next to the battery. If you see any wires cut up here in the battery, those might be it. I'm pretty sure the cables are still here so you won't need to look under the dash or anything. If you can't find them there or on the harness, I have the complete engine wiring diagrams as well as connector locations so I'll send u a pic with them. good luck

In fact here ya go, the first one is the conector locations and numbers. The conector you see tells you where it ends, when yo usee it, remember that it ends there, then it conects to the speend sensor wires and goes further down to it.
