Bazzaz Z-FiQS vs. TC - harness differences???

[QCD]

I have a K9 GSX-R 750 that has a Bazzaz Z-Fi QS that EDR installed for the original owner of my bike.
I was thinking about going up to the Z-Fi TC traction control unit.

I was wondering if there are any differences in the HARNESSES that plug into the Bazzaz QS vs. the TC unit?

Essentially, I am wondering if I would have to take all the QS harnesses out and put the TC harnesses in or are they similar/the same?
Can the QS module just be swapped out for the TC module? (couldn't be THAT simple, could it?!?!)

What do I have to do to upgrade?

Thanks for your help :)

basically the same but you wont have the plug for the tc adjust switch. but yes you can buy/find a TC box and plug right into a QS harness
