Wiring problem on 3.1 liter on 94 Century

[whacky43]

94 Buick Century 3.1 liter. Upon replacing rear valve cover gasket, I had to remove distributor, alternator, and un-clip numerous electrical wire connectors. After putting it back together, I had a connector remaining, and no clue where it clips to. It is light blue with red clip, very short, around a foot or so. It is labeled "ped" on top with the number "5" below. The cars runs fine, but the check engine light comes on and off. I have looked everywhere, and cannot find where this sucker clips to. If someone could help, it would save me the time of tearing it back down to find it. Thanks.....steve a.

My 94 also has an unclipped wire. I think it is for a diagnostic terminal. I beleive the connector is red.

If your check engine soon light on and you have checked most of the obvious stuff then...

There are 3 inline fuses which are hidden back inside the dashboad back and to the rear of the inside fuse box. I found out that at least one of these will cause multiple problems because it interrupts power to some sensors and the AC control relay. To get to these to look at them, you have to remove the glove compartment, fuse box, and then dig around behind the panel. The inline fuses are taped to the wiring harness and may be completely concealed with black electrical tape.

My car was showing 4 error codes (I paid Pep Boys $20 to read them for me). the GM dealership wanted $85) and of course the check engine light was on.

After I replace the VERY WELL hidden 10 amp fuse and reset my car computer, all of my error codes disappeared.
