There is no such thing as a timing advance wire on a 84 El Camino.
It's a brown wire with a connector. It's located on the firewall on the driver's side to the left of the power steering booster. Pull the connector apart before checking the timing. Be sure to re-connect afterwards.
AnswerMost of the time, the steps to take to set the timing are on the catalyst sticker under the hood. But first, you must get the vehicle into base timing (usually disconnect a wire from distributor). Remove distributor hold down bolt, hook up timing light to #1 spark plug wire, start engine, and align timing mark (0°) Once this is set, reconnect the wire you had to disconnect for base timing. Timing advance will automatically set itself. if it doesn't, you have a faulty timing advance mechanism on the distributor. You can check timing advance by pointing the timing light at scale (while hooked up to #1 spark plug wire) and rev the motor. Timing marks should move up the scale.On many GM cars and trucks the wire that you disconnect is solid gray in color, it is in the wiring harness on the firewall, the wire has a black plug for separating when doing the timing.
It retards the timing so the engine is easier to start. After it starts, it advances the timing back to an advanced position for best engine performance.

You have to unplug the distributor advance wire, it's a tan or brown colored wire, set to 0 (or up to about 8 advance) then reconnect the wire.
Not sure if the 95 is the same as the 93. On my '93 there is a timing advance wire you have to unplug (brown wire near the distributor on the firewall with a plug connector.) Start it up with the wire unplugged and set timing to 0 degrees BTDC. Turn off engine. Plug wire back in and computer takes over. There should be a sticker on the radiator shroud that gives timing and spark gap settings. From Haynes manual:On later models, the connector is located near the distributor (except for 1995 models; on these, it's located under the dash, below the glove box). Tan wire with a black stripe.
It will be a tan wire with a black stripe that breaks out of the wireing harness on the fire wall but close to the dist.

You need to unplug the advance wire located on the firewall on the passenger side under the plastic cover. It is brown with a black tracer then set the timing to 0 (zero). Plug it back in, reset the computer and you should be done.
buy a timing light. clip it to the #1 plug wire. loosen the bolt on the distibutor. Unplug the timing advance. start the engine Point it to the harmonic balancer and turn the distributer until the timing mark on the timing cover lines up with the mark on the harmonic balancer. Tighten the distibutor bolt. plug in the timing advance.
unplug the wire that says tach on the dist cap that's the one that reads rpm do this while car is off if this wire is unplugged it will not tell the computer to advance or retart the timing then set your timing to 8 degrees tighten it up and plug it in and that's how you set the timing
An advance timing light has a dial on the back of it so that you can set it to the correct timing setting, I.E. 4 degrees before TDC. If your timing index on the motor is unreadable due to rust or is just missing, this still allows you to set the timing. Hook the red lead to the positive battery cable and the black lead to a ground. Determine which cylinder is your #1 cylinder and then clip the inductive coil clip around that wire. Loosen the hold down bolt on your distributor so that you can turn the distributor , with some effort, and start the motor and pull the trigger. The light will tell you when it is at the correct setting. tighten the hold down bolt and re-check as the distributor can move sometimes when tightening the hold down bolt. Always either pull the vacuum line and plug it or unplug the electronic timing advance wire ( which ever your vehicle has) BEFORE trying to set the timing. Reconnect after setting the timing. There should be a label under the hood that will describe what the wire looks like and where it is located.
