I was always wondering, can an otherwise good throttle body be salvaged by dipping the wiring in the plastic dip coat used for coating tool handles? The coating would remain flexible for a long time, and assuming the bare copper wires were kept away from each other while curing the part could then be reused. I'd rather try these salvage techniques than spend $1700 simply because of rotted insulation.

I wouldn't try this for the engine wiring harness though, because of the sheer volume of wiring. I'm not that familiar with the throttle body, but I imagine there's a lot less wiring to deal with.
