I installed mine this winter on our E33 and it was a huge pain. There were some photos posted on this site which helped me to lay things out. My advice is to look for some flat surface either above or below your quatrant to mount the bracket on. Once you get that item in place everything else can be worked back from that point. Mine ended up being mounted upside down in front of the quadrant so since it was both upside down and backwards, I didn't need to switch the leads to get the rudder position to read correctly. Good luck and let me know if you want be to climb back down into the dungeon to snap a few photos.
