To snowmobile or not to snowmobile? Now that is a really stupid question!
Was it an LED test light, or one with a standard bulb, and did the intensity increase with volume? We could make a light intensity wattage meter, and use samples images to match the wattage. Sort of like the NAVY/MARINES hydraulic contamination patch test.
Long story short, you run hydraulic fluid through a sort of rice paper and you match the color when finished with a book. Mine never match any of the pictures. I prefer the laser unit more.
Ok sorry for going OT.
The bypass procedure depends on the manufacturer. Every HU I have owned just needed to be grounded. My fiancee's needed to have a cycle done. Installed a swtich which bridged the brake wire to a ground, flip it on, off, on, off, on and the dvd will play. Being as it is illegal to have a screen within driver view it works well if we get pulled over to flip it off (have not had to yet).
Shana the HU looks awesome.
I just finished my DVD HU install today. A little off topic, possibly, but this is how I tackled the parking brake. I could not find a SPDT relay anywhere, so I used a switch instead. It works like a charm! If you want the DVD to play, just push the button.
