Hi there, I am trying to retrofit the e61 rear suspension air springs into e46 touring because the rear end is to low for me and I would also like to control the rear height, I know i could get the kit that is made for e46 but I got all the parts for cheap from a friend and I already found a way to mount the original air springs to e46, but I am having trouble connecting the power and signal wires so that the compressor will charge and discharge when needed. Have somebody already done something like that. I am trying to get the higher rear ride because I usually carry tools in the back and I would also like to use the towbar for carrying bicycles.
