Yep, I've had the "lamp cord" or "hair dryer cord" wiring under the dash too. Had one w/floorpans so bad the guy had put in a sheet of OSB to keep you in the truck, naturally, it was all swelled up and soft and held the water to promote further rust. Had one w/chevelle bucket seats held in w/packing crate lumber NAILED to the floorpans (how in the heck did he do that?). BUT, the all time favorite, a PO had put electrical tape around cracked metal fuel line to carb and then wire around that (and seeing that didn't work), he made a little "catch can" out of an old cat food tin and suspended it with wire to catch the leaky gas. The catch can sat DIRECTLY on the intake manifold. Genius at work.
