VSS - where are you?

[pork chop]

I need to tap into the VSS for my overhead console. Someone suggested that there is a test lead somewhere, but I know nothing of it. Can someone tell me the best place to tap into the VSS wiring - preferably under the dash?

Thanks!

What will taping the vss for the overhead do anyway?

What I have found out is that the computer in the console is programmed to prevent false temp readings due to "heat sink". Basically, the temp that shows on startup will be accurate, but can only go down not up unless the computer gets an input showing that the truck is moving. So basically the temp gauge is pretty damned useless without the VSS hooked up.

That sounds pretty dumb, mine moves going down the highway

Yeah, the computer in the one I have is from a bit newer Explorer than the bronco base. The Bronco computer was DOA. I may see if I can fix it and put it in. Being that it is an older unit, it may be dumb...

DOA? Dead on arrival?

If you tap into the VSS, which the Explorer OHC is hooked into via its factory wiring, it will adjust the temp for when you are moving and setting still.

If you sit too long and idle, the engine temps will affect the sensor. If you are driving the wind speed on the sensor will affect it as well.

Yeah, when I bought the Bronco console, the guy swore that it worked fine. It didn't. I got it pretty cheap though, so I didn't sweat it. I picked up an Explorer console and swapped guts.

Anyone? Anyone?? Bueller???

Does the explorer console wire rite up like the bronco version?
