Could you detail how you get the mechanical part to work in case anyone else needs to do that? (Like me, for instance.) Thanks in advance.

For the honda SVOBoy had to upgrade to a completely different VSS, which required removing the VSS from the transmission and wiring up the new one. The downside of this is that his old gauge cluster would no longer work with the new VSS (the speedometer/odometer at least). He also just upgraded to a newer gauge cluster so that he wouldn't have these problems.

If you have a mechanical VSS it's likely that you also have an electric pulse that goes to your ECU. I'd track down a service manual with ECU wire pinouts to find out which wire it is.

Got a SuperMID from Yoshi last week and am tackling the install this weekend. I took a peek under the dash of my '92 Civic Si and had a couple of questions that I'm hoping other Civic/SMID users can help with.

How do I get the panel covering the ECU off?

How do I identify the injector wires from the ECU?

How do I find the VSS? It looks like all my wiring is tightly wrapped in harnesses. Which harness do I break into? How do I identify the VSS wire.

The power and ground shouldn't be a problem. Any other tips greatly appreciated.

Thanks,
Sean

You don't need to take the cover off the ecu itself, but to get to the ecu there is a cover over it. It's on the passenger side under the dash sort of up on the side by the door.

Those are ecu pinouts for your ecu so you know which wires are which.

Thanks Ben. I think I found it .



Now I just have to get the cover off and get at the connectors.

Good luck with it, for the MID. Alost makes me wish I was still addicted to gas,

Got the cover off and unplugged the harness. When I matched it up with the pinout diagram the A1 INJ1 color was brown as in the table but the VSS pin B10 was yellow/blue on the car but orange in the table. Am I okay with that?

Thanks,
Sean

Looks like the VSS is blue and yellow. Check out this picture for help locating the right wire:

The picture is looking at the ECU female plugs, so it can also be looking at the back of the wire harness plugs.
