bkeese: thanks very much for posting that info. It may help me when I finally get around to looking into this again.

Other new info I've learned since my 2nd unit failed (which I still haven't fixed/replaced):

- if the unit isn't receiving a high enough voltage, it won't work properly (one owner told me he fixed his by bypassing the brake cancel switch and wired power directly to the unit - with obvious safety implications). He did this after measuring the voltage at the unit and seeing there was a noticeable voltage drop when wired to the brake light circuit.

- the tech I spoke to told me the unit would work more reliably using a VSS signal instead of the coil signal (which is what I'm currently using)
