They learn tricks really well when you swap in an SD PCM. =)

How good are you at wiring?

You have to re-wire the harness and you can run an SD PCM.

The OBS trucks benefit from it because there are more things to program and tweak in the Sd's.

I'm not sure of the nitty gritty details though.
But, you'll spend a couple few hours re-pinning the wiring harness or making a new one from scratch.

I wish I had the tools to do some masterful work on harnesses.
I'd love to do some custom harnesses for stuff like that.
