trying to set base timing on a 97 Chevy c1500 with a 5.7 engine the wire to disconnect to set base timing is ?
The timing is computer controled and not setable.
YOU don't set the timing on a 96, its all computer controlled. If your timing is off then you have a problem somewhere else. So if you timing is truly off then what needs to be fixed is whats causing it to be off. The computer sets the timing based on feedback that it gets from different sensors on and around the motor. And secondly i don't understand how you could even know if the timing was off in that car. But my advice is, if you know the timing is off and its not throwing any trouble codes, take it to a dealer.
Probably computer controlled and not adjustable
Base timing is set to 0 deg with a scan tool. You can not do this with a timing light.
The timing should be set at 10:4.

Use a timing light with vacuum advance disconnected set base timing to 6 degrees
No. It has a DIS (Distributorless Ignition System)
depends on if your trying to set the time on the timing chain or trying to set the base timing for the computer. The base timing is fixed by the PCM/computer. for setting the time on the timing chain consult a service manual
timing gearsI've been told by more than one person that my '91 Cutlass Supreme has timing gears instead of timing chain. . I looked in the book and you should have a timing chain.
you don't the ECM will do it for you. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx You need to set the base timing on any car/truck that has a distributor. There is a tan/black wire that is usually under the dash down low on the passenger's side. This is the Electronic spark timing and the connector has to be apart to set the timing. That will put the computer offline while you set the timing to the specifications. There is usually a decal under the hood. Once the timing is set then reconnect the connector The base timing is set NOW the computer will take over from there.
