Another C1500 5.3 w/ 5 speed thread

[TexasEdition]

Truck is a '92 C1500 w/ NV3500

I know there are several threads/topics on this exact swap, and I've read them all along with many others countless times, but can never directly find answers to my questions, so here goes.

1. I'm converting my 5.3 harness to stand alone using lt1swap.com, which an external fuse block is constructed.

2. My factory oil pressure, temp, alternator, engine grounds, a/c, wiper motor, starter wires stay in place. Is there anything else? I should leave my fuel pump power/relay wires in tact and not run the fuel pump wire from the 5.3 PCM, correct?

3. Which wires need to be ran inside the cab and connected to the white/clear connector behind the glove box? Tach, TCC brake switch (I'm not sure what this is, but do I keep it if I'm deleting cruise control?) Does the park/neutral signal need to be kept since I have a manual transmission?

4. The VSS wires are simply spliced into my factory wires in my trans tail housing? What all has to be done for the speedometer to read properly? Will the reverse lights still work?

Sorry for so many questions, and posting yet another thread, but I'm going crazy reading through and trying to find everything. I just pulled my 305TBI last night, and ready to get the ball rolling.
