I was picking up a haynes for an s-10 at the library and thought to look at the metro book. It said vss was yellow with green stripe. It hooked up to the upshift indicator, etc, from the little switch behind the speedo.

Edit: it is yellow w/green stripe in a 98 too:

Hey thanks dcb. I'll grab that one and measure it. I appreciate the location info also. Sounds like less time on my head.

go2guy had an older metro as well, said he found the ecu/vss under the dash on the drivers side, above fuse block.

It would be nice if more people took pictures and posted them on the wiki (hint)

In my 95 Neon, I was afraid to pull apart the wires to the PCM/ECU. Fortunately I have a factory manual, so I removed the instrument cluster and tapped into the harness where the VSS signal goes into the back of the cluster. Only one wire comes through the firewall - from the #4 injector. Would have been more afraid of the airbag going off, but I disconnected the battery first ...

Thanks for your help and encouragement guys. I found it!!!
After I read the WHOLE MPGuino workspace one and re-read other helpful posts I got busy and did some digging. I read it all because I needed background and info for other things also (programing related). I had posted earlier (in error) that I tried green/yellow. In fact I did get the yellow/green (just typed it wrong) as suggested but it wasn't this yellow/green wire I was looking for (oh Obie Won). Ok so patience and perseverance shows that that there might be more than one of these color wires doing something else.

dcb- not sure if this photo is wiki worthy. A photo of last nights spaghetti dinner might do better. I will at least put an up date on wiki about the possible of more than one wire color in the same general area.



Edit: Ok, I don't know how to post photos. It is in my garage area.

Lol, thx. I can clean it up and add it to the metro page (make text white might help) in a section about older metros perhaps. Or if you want to take a stab at it that is fine too, on the left of that page is an "upload file" link, you upload it, give it a name to use in the wiki, then use the image syntax for the other images to make it display. We can roll it back if it gets totally hosed, don't sweat it

White Moss - '93 Geo Metro XFI

Just wanna say thanks for the advice I've gotten so are in this thread and on this forum.
Based on the spinning wheel trick I was able to confirm that I found my VSS (1991 Geo Metro). MPGuino also has good power and I seem to be getting fuel readings.
Trouble at this point is very intermittent data for speed. This weekend I'm going to try to make all my connections more securely and see if that solves this problem.
Speed will register accurately for a few seconds, then cut down to zero, only to come back from time to time.

If that's the only problem you are having, you may want to check all the solder connections on your board, and specifically the ones along the VSS line. When I soldered mine up I had missed one connection (or rather, it didn't make a solid connection when I soldered it the first time). Your board may be perfect, but it is something to keep in mind.
