New Speed sensor adapter
New Speed sensor adapter
I spent part of this week developing an adapter for the A4LD to use a commonly available and realtivley inexpensive speed sensor.
Installed it last night with great results, speedometer is dead steady, cruise and fule computer work the they should and tans shifts normally.
I have several long trips to make in the near future, a good test for the setup and if it performs the way I expect it too, I will make a nicer version of the adapter for Scoprio owners.
I could provide the sensor also, but they are easliy available locally.

Nice work. I have been playing with that sensor also last year but couldn't find the adapter with the right tread. Then i designed a circuit to use common Ford speed sensor (STANDARD MOTOR PRODUCTS Part # SC46) on Scorpio. Tested with oscilloscope and speedometer with good results.
So if we run out VSSs we have some solutions available.

Speed sensor
Jeff, what is the part number and place to get this readily ready speed sensor? I had to just switch out VSSs and will be heading to Carlisle. It is a long drive and would like to carry a replacement. Much appreciated!

Bump.....What is the latest on the search for a Scorpio A4LD vehicle speed sensor replacement? Thanks.

Thanks for the reply. Do you make the mounting/fitting and we source the proper VSS or do you make a plug-and-play part? What is the cost and lead time? Thanks.

Should have similar item up on http://www.merkurdepot.com
in the next 24 hrs or so.
Props to Jeff for the discovery and R&D that made these a reality.

Re: New Speed sensor adapter
Got my contour VSS sorted today. It is Napa P/N VSS327, I asked for one from a 99 Contour with V-6 and auto trans. The wires on the sensor were solid brown, yellow with brown tracer, and black with brown tracer. I couldn't find a good(read matching) wire diagram for that Contour, so I hooked it up matching all the main colors to my VSS connector. Solid black to black/brown tracer, solid yellow to yellow/brown tracer and solid brown to solid brown. It didn't work, but that could have had something to do with the 20 amp fuse in position 20 in the fuse panel being blown due some other cause(probably my old VSS shorting its frayed wires together) this fuse feeds power to among other things, the VSS, the kickdown solenoid, TCC solenoid(both for auto Scorps only) and to the turn signals. You'll still have hazards if this relay blows, but no turn signals, kickdown, converter lock up, or VSS... Once I replaced the fuse angels sang, and all was right with the world again
We really ought to put together a sticky of known good aftermarket Contour VSSes that work.
I think mine may have been a reman unit, but not sure as they didn't ask for a core, but it does have a Ford P/N molded into the plastic of the housing...
Now to track down the car side harness of the Contour VSS so we can make pigtail adapters, and thus gain warranty for our Contour VSSes, cuz I doubt they'll warranty it if the wires have been cut...

I have been using the vehicle speed sensor from a 1995 Ford Contour without any problems at all the colors almost match for Scorpio identically
