speedometer not working - Page 2 - ZR-1 Net Registry Forums

IF it helps, when I did my 91 dash in my 89, I used the 89 VSS (same as the 90 VSS)

everything worked, so I believe if you bought the newer connector and connected the correct wires it would work

I will see this weekend what the problem is. If its the vss sensor I will try to buy one somewhere. enough money will buy anything. I am thinking about the 91 vss sensor as a possibility. thanks for all you comments and ideas.

The '91+ VSS is GM 10456089 and is still available. You can/could also take that part number to most auto parts stores and have it used as a reference for an after-market that is much less. The connector will need changed or the pig tailed adapter I mentioned constructed.

When you go to work on this and if it's not just the connector.
Jack up the driver side of the car to avoid losing fluid when you pull the part.

SCV and side mirrors working?

edit: SCV and Cruise Control; not side view mirrors...

I was able to wangle 2 nos vss units for the 1990 zf 6 speed. How would I install this? Scottfab said jack up the drivers side of the car so fluid wont leak and replace part. Is it that simple?? Any infor on this from zr1 guru's will be appreciated. I found these two pieces at Tomco Inc. Apparently they were hiding in the stock room for who knows how long and I was lucky to have a guy who would go look for it. He had two so I bought them. Any info about installation would be appreciated.

Thanks, ed ramos #3028

It is that simple. Scott's suggestion for raising the left side will work BUT you mentioned several posts ago "race ramps" so if those are your intentions that would be a "no go" unless you can put your rear wheels on the ramps and then might be no need to increase the left side height. Raising left side only - use a pair of stands. Plan on a minor drip or two regardless.

Buy the seal I mentioned in the email and the replacement is very straight forward. One threaded fastener.
