Started on the ABS install over the weekend! welded mount to frame, ripped out all of the brake lines, ran rear lines forward to ABS, rewired ABS connector moving Pin10 to Pin6, removing pins 20, 24, 34, 39 (I couldnt figure out at first how to take them out, if there was a tab you had to press down, so I ended up yanking on the wires real hard from the back and they came out.)

Sorry John I should of done some pic's of the connector disassemble. I just used a eye glass screw driver to reach up in there and hold the tab to get the wire out. Pretty sure I had to do it from the wire side. Push the wire all the way in, lift the tab and pull gently, should come right out. If not you don't have the tab out of the way. I de-contented the entire wiring harness on my car a few years ago to remove all the unused wiring (air bag, emissions, HVAC, power windows, seats, mirrors etc.) so I have had some practice.

Need to find a mounting bracket for mine that I can modify.

My ABS install is on the back burner for now. For the winter downtime I am installing a Griggs watts link and a new 304 SS exhaust.

Plus the SCCA changed the class rules in CAM so to add the ABS now is going to cost me another 200 lbs. that I need to add to the car.

I also have a hybrid 8.8 and need to figure out how to get the ABS rings on my rear end. Need to call Moser to see what I can do.

Got FFR#48 on the road finally and ABS works!! I ended up upgrading the rear end to new FFR 2015 IRS which is based on the 2015+ mustang spindles/pumpkin including the 2015+ ABS sensors. Good to know that it actually works with the BOSS302 ABS module.

I have not tried it on track yet, first outing is April 15-17 @ NJMP. So far its not intrusive at all, only at extreme pressures it actually activates, and its fast, very fast pulsing.

Had to upgrade the lines from master to HCU to 1/4" size as the 3/16" size lines I was using before were leaking at the fitting (HCU is made for 1/4" line, found metric fitting that I drilled out to fit over 1/4" pipe)

Here is the final parts list I used for FR500S ABS (pics of install)

2007-2009 Ford Mustang GT500 ABS module (HCU – ebay has item, connector on back not on side, do not buy newer year model) $200
FR500S abs module M-2353-A (not sure if needed, calibrated for slicks, will try it in April 2016) $293.25
ABS Connector $51.24 Motorcraft WPT1356 Wire Assembly(relocated wire 10 to 6 and removed wires 20, 24, 34 & 39 that are not required
Tube nut fitting – 2 of 10M x 1.0 bubble flare to 3/16 line BLF-39C-5 (5 pack)
Tube nut fittings – 2 of 12M x 1.0 bubble flare to 3/16 line BLF-48C-5 (5 pack)
Tube nut fittings – 2 of 12M x 1.0 bubble flare to 1/4 (6mm) line BLF-46C-5 (5 pack)
Quantity =2 Adapter female 7/16 -24 inverted to male 3/8-24 inverted BLF-23C
Quantity =2 7/16-24 inverted flare nut for 1/4″ tube BLF-13C-5 (5pack)
3/16 brake line 25ft – AGS Poly Armour Brake Line PAC-325
1/4 brake line 25ft – AGS Poly Armour Brake Line PAC-425
Front wheel sensors (2 of them, $34.79 each) BRAB291
Front sensor mounts for FFR spindles – $45 made by Russ Thompson
{Rear wheel sensors (for 8.8 solid SN95 axles – 2 of them, $32.79 each) BRAN290} didnt use due to IRS install...
Wheel rear sensors (2015 IRS, 2 of them,$11.85) BRAB406


As for brake calipers, using Wilwood 6piston all around (4.04 area, 1.62/1.12/1.12), and using 7/8" wilwood master cylinders (2 of them) along with the balance bar to set bias.

Looking for a placement of my HCU and wondered if it must be mounted with the fittings pointed up like stock on GT500? Anyone know?

Sorry for opening old thread.

I would like to add TCS on current Ford Mustang 2005-2009 ABS module.
I can't find any wiring regarding TCS.. Can anyone help us to put diagram regarding TCS switch and wiring?

Thank you!
