How to check and adjust the timing
Disconnect the tan/black wire EST (electronic spark timing) by-pass connector located near the heater housing in the engine compartment on the S/T series, or near the distributor on all other V-6 models. Do not disconnect the four- (4) wire connector at distributor. Connect the timing light to the No. 1 spark plug wire. Check timing and adjust to "0" degrees BTDC. With the engine off, reconnect the EST by-pass connector and clear the ECM trouble codes by disconnecting the battery.

The answer given was not correct.the wire that you will disconect on a corvette will be a green wire that conects to a black wire on a tune port engine,Only a full size truck has a tan and black wire. and the timing is set at 6 DEG BTDC on the corvettte not TDC like the GM pickups with throttlebodies. The corvette dude.
