Default Have a wiring question -Help

I have a 95 Bonneville. Most of my wiring harness is plug n' play. Not too bad. But I have 'ONE' wire that I am not sure of and I will explain the best I can.

Between the firewall and the engine I have 3 plug-ins that are connected towards the bottom of the engine. I found where they go but I have one lone wire that 'may' be a ground. I don't like assuming. The three I connected were:

1) A plug connector plug-in into the steering fluid pump.
2) A connector plug-in to the Transmission.
3) A round connector plug-in to something - It matched up to its female reciever ok.

4) Now I have a wire (single wire) with a round metal ring (single wire). Looks like a bolt could go through it. I would say it is about 3/8" to 1/2" in diameter. Don't know what it is.
Could go over a bolt on the frame but then again - I really don't know. It could be a power supply source for somethng. Can't find any evidence of it being attached anywhere.

My Service Manuals have not arrived yet and I can't wait...LOL (I'm so close to completion)

Has anyone connected up wires (as I am trying to expalin) that may know what that wire may be and where it connects to?

Thank you in advance for your help in this matter.

John

I am almost positive (99.99%) it is the ground wire that attaches to a stud (on the block if I recall correctly (I can't rememer if it is a stud and nut or bolt into the block), just above the oil pressure sensor (which might be the round connector #3 on your list, or #3 might be the knock sensor) and a little more towrd the transmisson. That wire has a ring connector and is bundled in the wire loom with the rest of the connectors you mentioned.

The single wire with the ring connector he is referring to is a ground. We broke and replaced the ring twice on Ben'* (big_news_1) car. It attaches to the block, I just can't remember if it goes onto stud from the block, or uses a bolt that threads into the block. Somebody recently posted a pic of that wire here on the club, asking about it. I searched, but can't find that picture.

Default That one lone wire

Thank you all for your input.

I think it is a ground as well. It has all the ear markings that says it is a ground wire. I suppose I can connect it to any part of the frame where I can find a bolt or nut.

Somewhere along the line - I'll get some pictures of my Bonneville and post them. I have a little ways to go before doing that. Have to complete getting the engine filled with coolant, start and check the engine out, get my hood back on, clean the upholstery, polish her up and start taking some serious pictures. Then I'll have to have it to the aligned.

I was on a service call today and while on my way to New York (State) I saw a nice white Bonneville parked on the side of the road. Made me think of this club and if they could possibly know if this club exists.

You all have a nice evening and again, thanks for your help.

John
