I bought the 5 volume 78 ford service manuals in pdf form from Dave Graham Auto Literature a Ford Licensed product, and I cannot find a wiring diagram for a 78 bronco anywhere in volume 3 or 4, Body-Electrical. Can someone shed some light on where to find a wiring diagram for a 78 bronco in the factory literature? I thought it would be in the Ford service manual for sure. Am I missing something?

I'd imagine there is some sort of copyright infringement in doing that.

I got one from Helms a few weeks ago. It's on big 11x17 paper and was about $20 shipped? Worth every penny. I was going to take it to Kinkos and scan it to a pdf so I have a copy that can be printed again if something happens to the original I got. Wish I could find something similar for the engine vacuum lines. I have been searching for a Ford EVTM for a 78 Bronco. Anyone have a lead where to buy one?

No, that is just the electrical diagram. That is the same thing I got from helms. I am looking for the 1978 Ford truck and Bronco Electrical and Vacuum Troubleshooting Manual. It is a seperate publincation and it has the vacuum routing for the engine. I have seen them on ebay a lot but for other vehicles, econoline van, fiesta, T-bird etc..

ok, that NAPA search engine is really goofy; I got over 15 pages of hits on it with a search for 78 bronco... blower motor resistor yesterday using the Link I posted...now I tried that Link again just now and got the "We're sorry, but no matching products were found for "78 bronco blower motor resistor"."///!
Then I used an old part number to get to it again now using Google.. ECHLIN BR93
that is an ECHLIN pn by NAPA
it has a diff male blade config tho;
