its pretty easy, you hook the light up to the power source (your cars battery) then you take the clip that comes with it and attach that to the number one spark plug wire (drivers side wire closest to the front.) You will also have to unclip the computer from the car, this is done by unclipping a wire in the passenger side. I think that it is by the heater housing and I think that its brown or white with a brown stripe, I don't quite remember. Start up the car, point the gun at the harmonic balancer its the lowest biggest pulley on the pulley assembly... you'll see a mark and it'll flash at a constant spot on the timing marker. Adjust the timing forward by rotating the ditributor counter-clockwise and retard it by rotating it clockwise.

As quoted from me..


Setting the timing on the car is very easy to do. First buy a timing light and an offset timing wrench. (The bolt on the distributor is placed inconveniently if you don't have one. heh) That'll run you probably no more than 40 bucks.
To bypass the computer, look for a tan wire with a black stripe on it on the passenger side of the car. There should be a bundle of wires helt together with some black plastic tubing, and sticking out of that will be the wire. It's got a plug on the wire, just disconnect that. (Do this with your car off.)

To hook up the timing light...

Put the inductive pickup on the #1 spark plug wire. It's the wire closest to the front of the car on the driver's side of the distributor. Then hook the positive cable to the positive terminal, then the ground to any good ground you can find. Turn the car on, and after a few seconds the check engine light should come on. (Also be careful not to let the wires of the timing light get anywhere near the belts or the fan.) With the car warmed up and at idle, point the timing light down to the marks. As you've seen, the marks are made up of a bunch of triangle shaped wedges. The widest "valley," towards the drivers side, is TDC. Then, the peaks, heading towards passenger's side, are 4*BTDC and then, I believe, 8*BTDC.

Loosen up the bolt on the distributor, and slowly turn it either way to adjust the timing: Counterclockwise to advance, clockwise to retard. Don't jerk the distributor as it doesn't take much to adjust the timing. Also, when adjusting the timing the engine's RPM's will vary, so don't let that throw you off. After you get the timing set, tighten down the distributor and check the timing again to make sure it didn't move. Then turn the car off, disconnect the timing light and plug back in the EST.
