I am 17 and doing my first motor swap EVER and up till now I have done well. I got to the wireing and hit the issue of what goes where. I am swaping a 1995 4.0 out of an explorer 4X4 into a 1986 Bronco 2 2.9EFI. Any one thats gone through a simular problemb please help. Also if you have pictures that would greatly help. Thanks.

Using a 95+ engine greatly complicates things. My only suggestion is to get wire diagrams for both and get to work.

Yeah.....using the 95+ wiring and engine does complicate things greatly. You'll also need to find a way to adapt an EVAP sytem to the BII. You'll have to run a Catalytic convertor to keep the PCM happy.
What you need is a 4.0, wiring (all from the headlights to the cannon plug on the fre wall), PCM, Y-pipe, etc. from a 90-92 Ranger or 91-94 Explorer. This wiring is a little easier to adapt to the engine bay and ALOT easier to hook up.

What I ended up doing is buying the whole wrecked explorer and literally transferred every wire from the explorer over to the B2. Then I just plugged everything in! 
Took less time than sitting and figuring out each wire.

Yeah I was able to keep everything in, but I didn't have any controls to begin with. Everything is manual in my rig. I did have to do a little wire work with the dash gauges and small things here and there, like the headlights/breaks. I have no reverse lights, mostly because I got lazy.
My check engine light comes on only because I kept the BII Exhaust system and they only had one O2 Sensor on the Y pipe. The explorer had one on each header.

so you used the Explorer head lights and every thing
