OK, I bench tested my LI. With only 2 heads connected I got a "Check connection" or something alert. With 4 heads I got the "welcome" and it tested out OK with a remote although I didn't check all heads.
I'm installing it now. Have the front wires routed. (PITA getting through to the cabin) and started checking out the rear after disassembling the back of the friggin' car
So, I was thinking about clipping the RJ45 plugs so I wouldn't have to drill really big holes in the car but I noticed that 1 head is wired backwards from the other 3
If you look at the clear plug from the top (tang up) three have the red wire to the left and 1 has the red wire to the right...
I emailed Cliff, but I'm in the middle of putting it in and I have a long trip tomorrow evening.
I guess I never would have noticed it if I hadn't thought about clipping the wires.
