Great job, I just started the same project on my 2006 X30 trailer. I got the Hydrastar electric over hydraulic kit and it just showed up. I copied all the part numbers for the lights, thanks for that!
thanks for writing this up, I'm about to rebuild a 2006 x30 trailer and i believe boatmate uses all the same parts! going to walk out to the garage and check out my setup as i would love to rebuild the calipers for 55 dollars!
