tbi 350 to carb conversion....

[jumbo]

The wiring on my tbi is beyond fubar'ed, I'm calling Uncle and going carbed. At least for now, just to get it to run. So here's the skinny:

I have a 1989 GMC Suburban with the TBI 5.7L motor, with the 700R4 tranny (supposedly). My father in law has several carbed 350's at his house, he said i could use whatever i need off those. I know i'll need the intake (are there different intakes that fit the 89 block, or are they all pretty much the same?), a carb, HEI distributor, and fuel regulator to choke down the fuel pressure to carb. Anything else? I've done some research online and found some people that say i need a TV Cable or something? or a switch to lock the tranny? what up with dat?? I know it's not a 4L80-E because they only offered those starting in the 91 burb, so i know it's not electronic. Am i missing anything else? Please don't start with the "why go carb, you gotta keep that tbi" threads, as i said, the wiring for the tbi is beyond jacked (missing plugs, missing plug ends, relays on firewall with no idea what they're for, nothing labeled or color coded, etc, etc.), i just want the damn thing to run for more than 30 seconds so i can enjoy it for a little bit. I'll probably eventually rip out ALL the wiring and go with a new painless tbi harness and complete vehicle harness, or something, i just need it to run, like NOW! Any help will be much appreciated.
