Review on HQRP Navigator Lift Away NV355CS NV356KCS by Hco Cortes

I found out how difficult it is? Comes complete without instructions. A nice guy posted a bunch of photos online, but there are HUGE gaps in them, at least for me. Should I take these little hats off? Should new cable wires be twisted with wires on the machine? Will I wear little hats? (This cable comes without caps.) Which caps should I use, regular caps or screw caps? Here's the thing, if you're going to sell this item it should come with instructions - GOOD instructions OR there should be a warning that professional installation is recommended. I could save money, time and embarrassment if I knew it's difficult to do it myself.
