Works fine. I'm not sure it matters which wire is connected to the leads as it's just sending a signal to the ECU each time a notch on the crankshaft pulley passes the sensor but if it does I'll reverse them. My only criticism is with the butt connectors - they need to be crimped then the surrounding shrink tubing hit with a heat gun. If you're going to use a heat gun anyway I find it preferable to use Sopoby connectors (or other comparable ones) which contain a ring with solder that melts at a relatively low temperature. They require only one tool, i.e. a heat gun, to make the solder connection and shrink the tubing.
