Yes, it's a PWM, not an actual dimmer, and it requires both pos & neg inputs and outputs to work. First thing I tried when it arrived although I already knew the outcome.
John, the load resistor rating was 6 ohms. I just happened to have it in a drawer. Regarding ignoring or not minding the brightness variations, I'm (un)fortunately not yet old enough not to care! As I mentioned above, the inadequate resistor put out 9.25 volts whilst in parallel which over-dimmed the lights. Subsequent testing with the new "dimmer" showed that 10.5 volts was a satisfactory balance between reducing the heat enough but not reducing the brightness too much. So the issue of boondocking versus shore power voltage fluctuations was important enough for us to go for the dimmer option despite the accompanying difficulties.
Anyways - whilst looking for fish sticks today, I stumbled across a 48"x3/8" flexible drill bit designed for - yep - making routes for electrical cables! It's awesome (and $7.99 -v- $24.99 for the fish stick)!! So, the installation is complete (lots of polystyrene but not too much blood....) and it's sweet. 8) Definitely worth the effort so as always, thanks for all the assistance.
