Do you have the factory service manual?
There's a fusible link that with age is getting ready to just fracture; I had the kickdown relay (part throttle unlock, or torque converter lockup - take your pick which you call it) coming apart so it blew the link.
Do you have 12V at the Dark Blue/Green wire at the ASD relay when the power is on? How about at the red wire?
Have you checked for continuity to and from the ignition switch itself? If that goes bad, you may have some really weird symptoms.

Everything looks fine there
could a lack of power to the cab fuse box cause it not to start? Cause I have no power in the cab whatsoever
the horn works and I think the windows and locks work

Forgive me for being pedantic but did you actually open up the splice to look at the fusible link to see if it has broken/fused?

yeah I did and the lower splice was good but the Upper was kind sketchy so I spliced in a new segment to see if it'd help anything and there wasn't any difference

But yes, no power in the cab will cause it to not start, since the starter is switched through the cab ...
Do you have the factory service manual for your Dakota yet? May be time to start chasing the 12V and see where it stops.
