MAJOR score at the JY today! I haven't tried to read any specs on the CD relays, but they're probably big enough for an aux battery (my main purpose) and a winch (not something I'll do). The big sheathed cable will be perfect for a remote aux batt, and I'll probably slave a few other compressors off that one's switch for OBA.
All for less than a fillup. Turns out the big relay is
$87 plus sh 200A.
