Overhead Console Install WO/DIC...

[great white]

Oc means open circuit. You have a bad connection somewhere. Your 94 isn't going to have a vss signal at the radio an you shouldn't need it for just a temp/compass unit...

Dic needs a vss signal to apply the correction factor when sitting still for "heat soak" from the rad.

My 89 had a vss signal in the radio harness.

If not, it can be picked up from the drac/vssb module...

Ok I edited my post to remove the wrong info, I figured the only reason the VSS was at the radio was for the speed compensated volume an didn't figure that was available earlier than 96. My bad.....

Sorry if I should know this but what is drac/vssb module? And where is it located?

Forget the above post I figured it out. But which wire is the VSS?

Thank you great white! Really appreciate all the help but one last question: which one do I tap into for the vss signal?

You must be registered for see images attach

Just tap into the speedo wire from the vssb.

For some reason, i cannot find a vss input on a 94 radio.

It's entirely possible it does not have one.

I know my 89 worked, but it might not on a 94.

A quck search on google sould turn upthe right wiring disgram for you.

Cheers

Check for a bent terminal in the plug or receptacle.

Check for a popped fuse in the panel.

Likely something simple like that...
