This may be advice too late, but once you can get at the smart-top module, take off the outer plastic cover on the harness (the one that has the lock on it). Their harness just barely makes contact with the outer clip on. Mine wouldn't work at all until I removed the cover. Works perfect ever since. If you need help, I think the procedure is on their website under FAQ. If not, e-mail their tech support. Careful not to bend any pins. Good luck.
