I have been searching for brake mods and came across this. I knew the hemi rams had it we call it the dead head switch, but i didn't know we had it with the 4.7's and 5.9's. went down to the air strip to experiment. seems to be true. going to find this "wire " and do the snip mod.any one else know anything? can i get a heads up. so far i think its the #12, or #14 pin on the TCM plug.
