AT300 Auto Tuner or not?

Hi all,

Can I use an AT300 Auto tuner with my pcv on my2005 nightrod?

I am watching one on fleaBay at the moment here in the UK which at the moment is at a good price.

I know that the ones made specifically for our bikes are AT100 / AT100B but the AT300 also has 2 o2 sensors but not the connector to plug into the Harley wiring harness.

Just wondering:
(a) Is the only difference between the AT300 and the AT100/100B the plug to connect to the existing wiring harness?
(b) would it would work?
(b) how much work would it be to wire it in (no plug into existing harness)
(c) has anyone else ever used one on a vrsc*?

I am running with the Danmoto Highwayman (which has o2 bungs), K&N and topless.

Just don't want to buy if it wont work or would be a nightmare to get working.

Thanks all,
