Do any of you know of good (reliable) sources for OEM NEW replacement wiring harnesses specifically for FORD vehicles?

I have a 1988 Bronco II, 2.9L w/Air (doesn't work), 5-Speed Manual Transmission, 2-Wheel Drive, and an AM/FM radio that intermittently comes on or turns off at will (spooked me more than once!). That is not the reason I want the harness, though. I would like to begin a restoration of sorts on this vehicle, since it appears likely I will be driving it for quite a while longer, and trustworthy power is always a good thing.

Thanks.
