Final tweaking before dropping engine in.... Ran into an issue I need resolve. I am using a 99 explorer engine and wiring harness to include the charging wiring harness section. I am attempting to adapt this to the 2002 Ranger battery junction box. (BJB)

The 2.3 Ranger harness connecting to the battery juntion box has one common lead with both the alternator and positive wire from the battery connection attached. There is a inline fusable link in the large black and orange wire which comes from the alternator.

In the explorer setup there are also two wires going into the BJB but they have separate leads. There is not an inline fusable link, but instead there is a megafuse between the two terminals where the two wires connect to the BJB.

Attaching the explorer harness to the ranger BJB, I will have neither the fusable link or the mega-fuse option. I will also have to modify the connectors from the explorer harness to fit the ranger BJB.

Has anyone run into this issue before and what did you do to resolve?

Engine goes in tomorrow so any quick reply will be really helpful.

TIA-Rick
