Yes I still have headlights. All my lights work outside and in the cab. My dash doesn’t work which I don’t understand because it’s a Dakota digital and it runs right from the battery. But my radio doesn’t work, door locks, windows, and it doesn’t even try to turn over. I’ll check that wire and see what it shows me. But I’ve never had a head ache like this before.

That is because the only electrical circuits that are
not ignition switched are the ones that were discussed previously (i.e. head lights, tail/front parking/marker & plate lights, dome and courtesy lights, horn, cigarette lighter and a dash clock if so equipped). There are fuses that protect those circuits/components (excluding the H/L's which are protected by a 16 amp circuit breaker in the headlight switch). But - unlike all the other electricals in the truck - the line sides of those fuses are supplied directly from the battery on the upper RED 2 lead.
Everything else in the fuse block is fed through the ignition switch. There is one exception - the fuse for the brake/hazard lights is fed independently of the ignition switch - but it is branched off before the splice point for the 2 leads that go to the ignition. The brake/hazard fuse also supplies the circuit breaker for the power door locks - so since the locks are out, that branch leg is most likely dead too. That may help you locate the wiring problem (see the dwgs below). That should tell you that the loss of continuity exists somewhere between the bulkhead connection block and the splice point:

Your Dakota IP should not be wired to be hot all the time - it is designed to be ignition switched (and fused):
You must be registered for see images attach
Ultimately, solving this is probably going to involve some digging. For example, you might have to remove the fuse block from the bulkhead connector and/or break into the harness to locate the splice point to locate where the loss of power is occurring. After that it is a simple matter of repairing a terminal end or splicing in a new section of cable.
