I am working on checking out/neatening up a wiring harness for my dad's convertible right now. I have gotten almost everything on it labled with the help of the S5 wiring harness diagram, but a couple plugs have me totally stumped. I can't seem to find them in the diagrams??


1991 convertible harness- manual trans, with air bag


As yet it is totally unmodded. Best I can tell besides one wire missing its plug end it has never been touched at all. I imagine once I start unwrapping the harness I would be able to trace them back and figure out what they are but I would rather know before I dig in.


Here is the first one. This plug is in the same branch as the leading coil and associated check connectors. What am I missing here? I am pretty sure it is not involved with the leading coil. I can't think of anything else that sits right in that spot and can't find it in the wiring diagrams.







White plug, 4 wires (red, black, black/white stripe. green/red stripe)

Any idea what that is for??


The other one I can't figure out is a single wire coming out of the branch that goes to the main fuse block in the engine bay. It comes out of the harness as light green with a black stripe, and has a single pin connector taped down to the harness. When the wire comes out of that connector it is black. The end is missing so that makes it a bit harder to figure out.







The piece of the wire with the tape hanging off is a rubber isolator like the wire was held in a metal bracket at that point. I don't think it plugged into the main fuse block but must have went to something pretty close by.

Any ideas on this one?



I'd take any help I can get on these guys I am sure its something super obvious I am missing but its driving me nuts!


Thanks!

 

First plug answer:

 

Dude thanks a bunch! I swear I had looked at that page like 10 times and didn't notice that! No wonder I didn't recognize it. I don't deal with airbag stuff much.

 

Ok I am pretty sure I have tracked the cut off end wire to be for the power steering pressure switch.

 

yes it is the power steering plug the other let me get back with u i know what it is just having brain fart
