you would need to run those circuits through the gen 4 BCM and have all the comm lines hood up so that the ECM sees the signal that it is being toggled on and off

not to hijack but i been wondering this ever since i did my swap...and now seems a perfect time to ask... is tow/haul mode possible through a simple switch (which i doubt) or is it through "class 2 data" which is obviously more involved.... (which im pretty sure it is). id love to add this to my dash but if its through " PCM talk" then its not gonnna happen in my case....
Like Tumbler in "Gone in 60" I'll drive anything with wheels or without
