1995 sonoma 4cyl 2.2l 2wd 5spd man. loc'n of switch on trans for backup lights.

Have a look at The Brake switch...It well be on your Foot Brake have a look at the brake pedal..There is a switch near the top of the arm and it works with a pin arm that rest against the pedal it might of come loose with working on the clutch..some you can adjust maybe all or might have lost the power connection I hope it helps you...I might be wrong...But its a start good luck

Here's my guess - check the steering column. There (might) be a pin that moves the switch when the gear selector is moved.

thanks for the replies, i've actually found what i was looking for after talking to a mechanic friend, just needed to get the truck up on the jackstands to be able to get under far-enough to see the switch on the side of the tranny, jumpered a wire between the two wires to confirm that it was indeed the switch that is dead (a 10-15$ part) easy fix thanks for replies
