We got the Raptor Performance dual mode shift light setup installed on the a few weeks ago. We got to test it out at the Ford vs Buick shootout, so far it seems to work pretty damn good! Way better than the N2MB WOT box and the MSD Window Switch box we had. I kept the N2MB installed in case we ever decide to use the 2 step and the Transbrake some day. Hopefully, it’ll actually work for that. Other features such as its shift light and shifting function (window switch) never worked right so I have very little hope for it. The MSD Window Switch box partially worked but it wasn’t often not consistant on the shift times. I removed it along with the Autometer Tach Adapter to make the MSD function. The Raptor shift light doesn’t need the tach adapter at all. All that stuff will be up for sale very soon.
Back to the Raptor Dual Mode Shift Light setup. Not only does the Raptor shift light work by flashing a light at a desired RPM, but in dual mode it’ll activate the air shifter (or whatever else) at the desired RPM to shift the transmission through the gears when going WOT at the track. This essentially makes the Booker's Transmission Reverse Manual Valve Body TH400 fully automatic at WOT. Hopefully this will help consistency in the future. To make all this work smoothly I had to bump up the pressure on the on board air system with a 120psi/140psi pressure switch and a new MAC valve.
Wiring Installation was fairly straight forward on the Raptor Performance Shift Light. They provide instructions specifically for a Gen 3 Coyote however, some of the wiring did not exist on my car. Most likely due to it being originally a 10R80 car, not a MT82 car. First, I connected the green wire of shift light to coil driver #1 directly which was the white wire with violet stripe on my car. (the PCM pin suggested by Raptor did not exist on my car) Second, I connected the red wire of shift light to 12 volts switched source which would be my Painless Performance Products AUX fuse box in my case for its own fused power source. Third, the Black wire of shift light goes to the ground of the vehicle. Fourth, for the dual mode shift light to function, connect the white wire of the shift light to pin #51 on PCM, 90 Pin connector, C175T (brown wire with green stripe stripe). Finally the fifth and final wire from the shift light which is brown, connects to a ground source to whatever controls your shifter. In my case I connected this wire to the ground source of my solid state relay. This relay is setup to be ground activated on the switch on the steering wheel, and now via signal from the Raptor shift light. Which ever goes off will activate the relay therefore shifting the transmission. Once all that is done, Set the shift light to "1 cylinder" mode and program the rest to suit your needs.
Please note, on step four, I was concerned if that pin would exist or even function on my setup since our car originally was a 10R80 car now running on a MT82 tune for the TH400 swap. Apparently it still works and functions like it should thankfully. At least Ford put the VSS sensors on the front wheels on the Gen3s and not the transmission like previous years.
For the physical installation I choose to mount the shift light at the cluster for a clutter free install. The little panel between the Tach and the Speedo pops right out making modifying it a breeze. Drill a couple holes, mount the Raptor supplied 3D printed mount, and run the wire harness behind the dash. Couldn’t get much easier than that.
Hope this helps out any Gen 3 Coyote Mustang guys wanting to add this mod on a TH400 swapped car. Per the usual with this platform, I found no info on doing this mod when I searched. Figured I’d share this to maybe help someone out with a similar build. Good luck.
