2wd vs 4wd 85 wiring harness

[Silveradotim]

Hello everyone I'm in the process of putting my 1985 Chevy 1/2 ton 4x4 back together after a 3 year frame off restoration I have a 1984 2 wheel drive wiring harness under the dash, I'm wanting to know if I can plug my transmission and transfer case harness into the fuse box and everything will work??  I'm very stumped on this and I can't move forward, any help would be greatly appreciated

It should work.  I would verify you pinouts,  Why not use the 4x4 harness?

because the 2 wheel drive harness I have is in alot better shape....there is one plug on the transmission and transfer case that is killing me though It's the only thing that I cant figure out It runs under the dash it's like a green white and blue and somethin else.... have any ideas??

I should have been more specific it's on the transmission wiring harness it's a plug and it runs under the dash.....black plug with green white blue and I think brown wires I don't know where it goes???
