I installed some seat vibrators....
My install was based off of the need to keep the car nearly completely stock if need be. I don't want the flashiest one, i just want a nice clean, and drill free install.
I bolted these plates/arms to the crossmember, and then bolted the other plate to the box. The arms are L shaped, and have a bracked that swings around to prevent them from falling out.
I was not able to fit the power wire on my postive post. I found this very nice top post terminal for 1.71 at K-mart on thanksgiving day of all places. It'* mainly designed to clamp wire between the two screws, but it'* a nice way to cleanly add 2 ring terminals to the top post, or one bare wire.
It runs along the quarter panel, and this keeps it out of the way for battery removal, and coolant lines.
2 zip ties hold the base plate on the fuse holder, it doesn't move at all. Nothing drilled at all. I may attach it better to the tank sometime but this works great.
There was no good line between the quarter panel and the Strut tower, so i ran it along the bottom by the other wire looms, cables so the belt doesn't suck it in.
The power wire enters the fender here. It drops into the door joint area, and enters the cabin through the door accordian tube, where all the doors wires run. It keeps everything sealed, and my firewall intact. You can't see it, it doesn't run on the door at all, and it'* removable.
After this it runs along the door sills, underneath the rear seat corner, and into the trunk. It pops out in the corner of the trunk behind all the carpet.
