‘93 Mitsubishi Diamante, Setting Ignition Timing
Q: How do I set the ignition timing on a ‘93 Mitsubishi Diamante with a DOHC engine after installing a new timing belt?

A: If you look just behind the battery on the firewall, you’ll see a two-wire connector with nothing connected to it. In this connector, there will be a yellow and red wire. Grounding the yellow and red wire causes the engine computer to stop controlling timing, returning the timing to what is referred to as base timing. While the computer is in the base timing mode you can adjusted the timing as needed with a timing light and by loosening the bolts that hold the crank angle sensor that is mounted on the end of the rear camshaft and rotating it just in the same manner you would if the engine had a distributor.
