So my buddy’s 84 Bronco II was stolen, then recovered with extensive damages. Glass broken and wires cut for salvage, and I mean every wire in engine compartment, behind dash, etc. only the wiring plugs remain. Been looking for electrical diagram of engine harness, with no success. I plan is to make a cheap off road for my wife to gain exposure to our sport. She’s very competitive and will want her on ride, so my thoughts go to the Little Bronk. My question is this: what are the essential wire connections, obviously the firing systems, some dash connections for vital gauge info, maybe trans, MSD box and coil, fuel pumps, lights. If I could fine a complete wiring harness, this would be easiest way since old plugs with colored wire Stubbs remaind. As of yet no luck on complete harness. I looked at various vendors’ universal kit but more than what I think I need. So tell me what wires that need to be complete to provide running and operable truck. Thanks for ideas.

in 84 the BII came with a Carb'd 2.8. Stayed that way through 85. Wasn't until 86 that Ford put in the FI 2.9. This will make your wiring and harnesses different between the two.

If you are doing something custom I'd suggest sourcing something you can pull a 4.0 from. Specifically any Generation 1 Explorer works well. I did this years ago on an 87 Bronco II. Having a donor vehicle is the trick for ease. I used the entire engine harness from my donor when I did the swap. The 4.0 is the same size block and mounts without any modification. At least it did for the Fuel injected models... I cannot confirm this for the 84/85

The other option is to do a 302 conversion. James Duff has a ton of mods for Bronco II 302 swap info.

Anyhow, best of luck!

Curious? Where are you located?

Cheers,

Wonder if one out of a Ranger from same era work. I would be checking out local junkyards.

It would depend on the options,but the basic harness would be the same,for the dash and underhood.
