Searched but didn't come up with much about where exactly the grounding points are on my 93. Can anyone point me to a post that describes how to get to them so I can clean all the ground contacts? I am particularly interested in the ground for the dash which is supposedly somewhere in or near the driver's side footwell everyone keeps referring to in various posts. I need a real good description of exactly where that sukka is! And a pic would be awesome!

I quickly looked around on mine and didn't see it. Is it under the carpet or where? I have the FSM, but it wasn't real clear to me where they are, and especially that one ground for the dash. I have the intermittent dash problem, which I am going to fix, but I want to clean that ground contact point first. I also have a new headlight switch assembly going in at the same time.

 

This isn't in all FSM's but check the 8A-201-XX of your FSM OR just after the grounds schematic the following page may have an image reference for G201 in that section. Some years yes, some no.

 

Thanks for posting that image since I have the FSM for my 1993 Ruby 'Vert. The odd thing is that I have noticed that wire a few months ago (blue). Although it is attached like the diagram, it is only about 1/2 long and is not connected to anything. I thought maybe it had broken off a wiring harness and wondered what the function was. My car is bone stock, no mods and always wondered what this wire is for. Any thoughts would be appreciated. I could take a pic' and post if necessary. TIA,
Mark

 

Thanks much for posting that image, WV! I seriously appreciate it. If that image is in the 93 FSM, then I sure as hell can't find it. I looked at both section 8A in the second book on ground distribution (all it has are schematics), as well as the little section on electrical in the first book. Nada. So mine must be one of those years that doesn't include it. What year model is that image for?

 

Mark, is it possible someone could have regrounded the harness to a different point and cut those wires? Or it might be possible to misinterpret that drawing, cause I am still having trouble understanding whether that G201 is on the firewall, sidewall, or inside the driver's door panel. Looks like it could be either. Ugh.

 

CL:
First, let me apologize for possibly hijacking your thread and really appreciate your reply I am the 2nd owner of my '93 'Vert (had her over 15 years) and pretty much know the car inside and out but anything is possible. I only have one (1) wire like the illustration and it is attached to the kick panel, blue in color and easily accessible and visible. Although there are two (2) wires in the illustration, I can only see the blue one clearly. I'll try to post some pic's up but it looks like G201 in the diagram. Since my 'Vette and FSM is at my warehouse, with my other cars, about 25 minutes from where I live I can't check on that now but will try to post ASAP. I spent most of the day replacing a 6 year old Delco Battery and while I had the side panel off, cleaned two other grounding points. One was the black wire that comes off the negative ground to the battery and the other was the ground strap that goes to the starter. Although I don't have any issues I thought I might as well be proactive and although I have only 30K on the odometer and a garage queen, the grounding on the two wires were slightly corroded. Removed the wires, carefully and wire brushed, cleaned and reattached with a dab of electric contact grease on each contact point (both were attached to the frame rail). I had read in some other post's that these two grounds can cause potential problems. Like you, I would like to get to all the grounds, especially the ones that you don't normally have access to. Have a nice 4th and I'll try to post some shots of that blue wire since it is driving me
Regards,
Mark

 

There certainly shouldn't be any "BLUE" wires used for grounds unless it's a splice by a previous owner.

OP - that image is from a '96 FSM but I believe it's in others. I didn't look but in one other I had there was only a reference to the location with no note as to a 8A-201 image.

That location is a typical location chosen by GM for nearly every production car line through the '90s. Might be #'d differently but would always be a G2XX (G - ground, 2 - zone in the car, xx identifier)

 

It's on 8A-201-22 in my 93 FSM.

PS
Figure 45 - LH Kick Panel

 

I agree but will take some shots and post. I'll check my FSM for blue wires in that area.

Thanks for the info. That really helps.

 

Yep. Well I'll be damned. There it is. Under the "Component Views" page, like 200 pages away from where it should be.

And yet even so I am still unclear whether that's on the firewall, sidewall, or embedded in the door panel? Could someone say please? I am like seriously stupid I guess.

 

It's down on the panel to the left of the pedals inside the car.

 

Ok. So from the looks of that pic, it's on the sidewall just in front of where the door starts... I think... I'll find that sukka if it's the last thing I do!

So is that above the carpet? Lol. Ok ok, I'll go look again. Thanks a million, man.

 

It's under that plastic piece that runs along the bottom of the door opening.

 

I went and looked again, but it's getting dark out, so will have to do tomorrow. So you're saying it's down that low under the bottom door strip? But in your pic it looks like it's up higher on the sidewall in front of the door? Oh man, I stay confused.

 

Kinda Both.

I'll add a picture to my post about 30 minutes.

On the right side near the top.

 

My mistake, the wire is black, and just forward of the G201 (two grounding wires). I will take a shot and post, but any idea what wire harness it would ground to. It is very thin, much smaller guage then the G201 grounding wires. I have the FSM and don't see a diagram of this. It looks factory and not aftermarket.

 

Here is a link to another view of the grounds on the C-4. Not sure what specific year it applies to but hope this helps.
