Hello. I didn't readily see this question in another thread, so here goes...
After buying a U.S 2004 L322 this past week (my first Rover), I installed the 7 pin Atlantic British trailer harness today using the green relay (VIN is below 4A999999). I later started the vehicle and went through the gears, although didn't actually move it, in case an engine cycle was of relevance here. Afterwards I checked the hitch plug's 7 pins with a multimeter to see what they're up to. I noticed that when the left turn indicator is operating, ALL THREE of the "Left Turn/Stop," "Right Turn/Stop" and "Running Lamps" terminals were getting the same pulsing signal. With the right turn indicator operating, same thing: all three terminals were getting the same signal. If this was an old pickup truck, that would suggest that BOTH rear trailer lights would be blinking when turning either right or left (basically operating as hazard lights), in other words, a malfunction.
I don't currently own a trailer to connect to, but may purchase a 2006 7-pin camping trailer next week, hopefully without LED lamps. Are the terminal signals I'm getting normal considering no trailer is connected? In other words, unlike that old, simpler pickup truck, will the L322's black box properly sort out the signals once an actual trailer's electrical system is plugged in? Also, my understanding is that there's no shop "reprogramming" required for a 2004 in this situation, and that the vehicle will automatically adapt: hopefully someone can confirm that.
Lastly, AB inadvertently gave me a kit without the mount and ball as requested, so I may just use whatever "extended" 11-13 inch, 2 inch drop mount that's available from Camping World down the street. Has anyone had experience with those lengths? (I'm aware of the 11 inch limit, but will be towing 200 lbs below the max tongue weight and 2,700 lbs below the max trailer weight.) And I'm leaning towards a wireless brake controller (none purchased yet) -- no L322 electrical system complications!
But in its CURRENT state with the cargo area blue wire unused, the new harness should be sending brake light signals to a 7-pin trailer, correct?
Thanks in advance.
