OK if you look up under your dash and look at the back of the brake pedal you will notice two plugs connected to it.

You will need to concentrate on the bottom one.

There are two wires on this bottom plug. Four wires for the column shifters.

The red wire with green or maybe brown stripe (color blind see pic) is the wire that talks to the ECU for both column and console shifters. It tells the ECU that you are hitting the brakes and disables the Throttle 90%.




If you toggle the red/white wire at the ECU this mod will work and so will your brake lights. If you do this mod at the brake pedal (red wire with green or maybe brown stripe (color blind see pic)) it will work but your brake lights will not work. I find this convenient as your next victim cannot see you doing a power brake.



I went a different way. I wanted an OEM on/off switch to match the rest. I bought a Cargo light switch and used that. However. There are 6 pins on the back of this switch. You will only need to use the 1st and 3rd pin for the on/of mode. See pic.. I cut the 2nd and 4th pin off as to not interfere with the others. I also wanted to paint over everything on the switch but the letters “GO” but I could not figure out the right pins to light the switch so I painted the whole thing black and abandoned that idea. I also had to cut away the female plastic harness plug to get good access to the wiring pins (see pic).



For the ECU route:

disconnect and remove battery.

remove battery tray (4 bolts)

pull out bottom ECM plug

cut open harness and find red wire with white stripe.

mount any type on on/off switch in cab (where ever you want the switch)

run wires from switch through firewall and into engine bay(near fuse box)

cut the red/White wire, and connect the ECM end of the red/White wire to the acc. side of the switch and the other end of the red/White wire to the supply side of the switch, tape 'em up and re-assemble everything in the reverse order, your done.



for normal driving operation --- switch in "on" position

for burnout mode --- switch in "off" position.



For the brake pedal route:

disconnect battery ground

Remove panel under the steering wheel.

Remove blank switch cover.

Install your modified cargo light switch with wires attached

Replace panel under steering wheel.

Cut red/green or red/brown wire on the bottom brake harness

Connect one end of the switched wire to that wire and the other end of the switched wire to the other cut end, making a circuit you can shut off.

Replace panel



Another note: Even though your brake lights wont work it don’t matter. Once you have launched and killed another hemi you simply turn the burn out mod off , enabling your brake lights.



The switch







The pins. You only need to use the 1st and 3rg pin (left to right)







Cut plastic housing to gain better access to the wire pin..









Cut off the 2nd and 4th pin and connect patch wires.












Remove panel under steering wheel.














Remove blank switch cover and install new switch





.









Here is the red/green (brown) wire you need to cut and interrupt with the on/off switch











Connect the wires and use some solder or some other means to secure them. I twisted the wires together then used heat/shrink stuff to secure them.




Done!







Some final thoughts…. When you go test this give yourself plenty of room your truck will take off like it never has. Turn off the switch (cutting off the brake signal to the ECU, turn off your VDC (if you have it). Apply brakes, accelerate while braking to about 2500rpm, let off the brake and mash it. If you have a true trac installed look out you will fish-tail and be out of control in no time on wet pavement like I did today.



Video soon!

I start out with grand intensions then get sidetracked and only post 1/2 of what I had planned especially if things are not going well.
