18436572 0 degrees BTDC The base timing must be set to 0 degrees with the timing connector conduit disconnected to bypass automatic timing. With timing set to 0 degrees, reconnect the conduit and the computer controles the timing. This conduit is located on the wiring harness on the right side of the firewall, under a Y shaped plastic cover. It is a one wire connection that protrudes from the wiring harness. It is a tan/black stripe wire.

Where is the wire that has to be disconnected to set the timing on a 1998 Chevy pickup?
First place there is no need to set the timing if the distributor has not been moved. And there is no wire to unhook.The ignition timing is controled by the ECM / engine control module. If the timing is off you will have a check engine light on. If the light is not on, then the timing is correct. No need to bother, The computer is taking care of it.You have to have a OBD II engine scanner to set the timing.
