I bought link plus used from a guy over on nasioc. After waiting 2 months to actually get the thing I can't get it to connect. There's a couple things that could be causing this problem from what I can tell.

1.theres something wrong the ecu aka broken
2.I made a plug and play harness
3.the serial cable is bad
4.the ribbon cable is messed up
5.somethings wrong with the serial link
6.I still have my piggybacks hooked up while trying to connect
7.problem with the labtop? windows xp?

Is anyone running link plus and is willing to help me out? I'd really just like to plug my link into someone else's car to see if it works.
