Does the 12200411 PCM have Tow/Haul Capabilities?
Im looking to swap in the 0411 PCM and would also like to add in a tow/haul button, does anyone know if it is doable? If so, does anyone know which pin it would be?
I have the full pin out diagram but I cannot attach it here. It is in excel.
Here is my thread on EFI Live Forum, you can view the diagram there. 0411 PCM Pinout Diagram

It does but it isn't used. meaning you would have to pin it and hook it up yourself.
I wouldn't do it just yet since that info was on an LS1 Pcm. Yours could be a different pin. Still trying to look.
The guys on EFI should know. DRX or whatever his name is is usually good with that.

The pins vary in their use depending on what operating sustem is in the PCM. Example the pin used for the second fan speed for the corvettes and f-bodies is used for the recirculation door on the trucks with only a single speed fan or no electric fans. So you need to use the pin out for what ever vehicle the operating system you're running. Just adding the wire to the pin, most likely will not make it work. A lot of vehicles with the tow/ haul option, control it through the BCM instead of the PCM, and send the signal up the class2 data or the CAN buss to the PCM. You would also need a dash cluster that would tell if it was engaged or not, since most of the tow switches are monmentary contact push once to turn on, push the second time to turn off
