First, let me start by giving credit where credit is due. I got some of my information for this write-up from YOUNEEQSVT in this thread.
I've taken the time to document the install process for use by the masses. The whole thing can be done in a day, provided you don't hit any snags or break anything. It is advisable to have a friend on hand to assist with the brake bleeding. This how-to will assume that you have moderate mechanical skill and is not meant to be a replacement for a technical manual. You will more than likely have to evacuate the AC system to get proper clearance to remove the brake booster, consider the cost of re-charging the system into your budget before you decide if this mod is for you.
First, a list of the parts you'll need:
TCS Controller from second gen Mercury Mystique or new edge Mercury Cougar
Ford part number: 98BG-2C285-CB
Bosch part number: 258 090 50843 4
Hollander interchange: 545-1374
A quick search of the used car part websites will turn up quite a few hits for this part. Do yourself a favor and call the yards before you order anything. I had to ask five yards to visually inspect the part for the above numbers to verify that it's the correct piece before finding one that actually had a TCS module. I paid $50 + shipping for a unit out of 2000 Cougar with 80k miles.
This is the information for a NON-TCS module, I’ve included it to help prevent you from purchasing the ABS module you already have.
Ford part number: 98BG-2M110-BA
Bosch part number: 404 184 50132 7
Hollander interchange: 545-01462B
Here are side-by-side comparrisons of the two units. The TCS unit is on the left, the non-TCS is on the right. Note how the TCS unit is a little larger.
TCS sticker is a dead give-away that you have the right part.
Note the identical pin-outs. The Ford part number is located between two of the brale lines on this side.
Bosch part number stickers
Side mounting bolts
Defrost/Traction Control switch
Ford part number: F8RZ-2C418-BA
I ordered this part from Tousley Ford in the summer of 2010, if I recall it costs approx. $25. If you can't find the defrost/traction switch and you're thinking about using the front/rear defroster switch from a Modneo (they fit in the same location and they're everywhere on eBay UK), it won't work. The front defrost switch has one less pin than the TCS switch.
Enough brake fluid to refill and bleed the entire system.
Is your Contour able to add this feature?
So far it's been confirmed that ECU models SFG0 or SFG2 will run TCS, others may work but these are the only two that I could find information on. You can verify this by removing the ECU from the passenger foot well of the car and checking the stickers. If you do this mod with a different ECU and it works, please let me know so I can update the post. Here's how you check your ECU:
Use a 10mm socket to remove this bolt in the right side of your passenger footwell.
You should see this sticker behind the white bracket.
If you don't find a sticker there, you'll have to remove the entire ECU. Open the hood and look behind your passenger side strut tower for this bolt.
Use a 10mm socket, universal joint, and 10" extension to loosen that bolt and release the ECU from the harness. Go back under the dash and gently pull it out of the firewall. This is the other sticker that will identify your ECU model.
Your car must have an extra pigtail hidden behind the defrost switch. The easiest way to check this without damaging the gauge surround is by using the short end of a credit card to pry the switch assembly out. My E1 had the pigtail, a friend's E0 2.5 SE did not.
Your car will also need to have an bulb installed behind the "Traction Control" light on the instrument panel. This light will not come on unless the TCS module is installed in the car, so don't assume that it's not there just because it doesn't illuminate at start-up with all of the other warning lamps. If, once you've installed the TCS module and you're still not getting a light, you will need to pull the gauge cluster to investigate. My car had the bulb, the afore mentioned SE did not.
Now, a list of the tools you'll need.
1/4" and 3/8"
1/4" Sockets & Accessories:
3/8" Sockets & Accessories:
3", 6", 10" extensions
13mm (x2, although the second can be substituted with a 6" crescent wrench)
3/4" and 7/8" AC line quick-disconnect collars
Various flathead screwdrivers or other small prying tool
Nice to have but not necessary:
Manual brake bleeder pump
Magnet on a stick
Several shop rags for containing and cleaning up brake fluid
