Whatever you do, before doing anything, Check, recheck, double check, & double recheck, try to think at least 2 steps ahead, ie; if I do this what will happen, if I do that, will it work, if I have it on a jack (of any type), will I also have to raise the MH, It would certainly help if you can find an installation manual.Have lots of band-aids available for your fingers. :(
GOOD LUCK
