Battery Cable Ground Wire

Can someone tell me where the smaller ground wire coming from the battery terminal connects to?

I would say it is the body ground, should be a screw someplace near the battery.

I can see that the "flag" and provided screw bolt to the chassis, and the end of the battery cable connects to the engine block.

My question is concerning the smaller and shorter black wire, attached to the battery terminal. Where does this connect?

The longer wire goes the front passenger side of the block. The short wire goes to the fender.

If this is for an 85 truck then you have the wrong set of cables.

It is the body ground at the fender for an OBS and Brick nose:

That connection is the computer ground for pins #40 & #60. The truck will not run without that connection.

My 1985 was converted over from EEC-IV/feedback carburetor to the Duraspark II ignition. So it looks like I don't need that connection at all.

Thanks for all of your replies.

It may not hurt to screw it into the fender so you have a good body ground. The center of the cable clamps bolts on to the frame and the end of the cable bolts to the engine block or starter mounting bolt.
