It sounds like you are running an auto transmission. Those two wires go to a VAC TIP IN switch. There should be a vac line going to this switch connect to intake vacuum. If I remember right, it senses sudden changes in manifold vacuum and the switch would momentarily close. The ESC used this signal to control the spark on sudden vac changes. If you bypassed your ESC, then the switch does nothing. You will see TIP IN switch on the original emissions sticker (if you still have it). Mike Ervin explains the operation in his link. Good luck, Greg.
