OK so whats been taking awhile is the wiring and not that its hard just methodically time consuming to make sure the magic smoke stays in. First did the main power distribution for the additional power requirements like twin E-fans, ECU, Twin walbro 450 fuel pumps etc. For that I ordered a china crimper for 35$ works great just like with any cheap item though needs a little finaggling on certain sizes.

I was able to use the stock tahoe starter wiring harness cut down to hit the alt, batt, and send a run over to the distribution block via C/B this way.

And pass side to the stock starter relay i changed out to a golfcart continuous high amp relay as the starter solenoid although can handle amps it cant handle continuous use at 5 amps draw. the golf cart pulls .5amps. reason for the relay is to have both constant power and switched power for ECU, fans, relays, pumps. all the stuff you want to ensure turns off at key off to not make a parasitic draw.

I then setout to clean up the body harness in the eng bay and chassis as 30yr wires are fine if protected but the plugs were straight garbage. So used my delphi weatherpacks to make wiring clean and servicable.

Now thats a taste of the wiring harness renew on the body side. more will be done as i get to it and tie all the systems together. But then it was on to the pnp harness for my Engine. Which yes it was plug and play but i wanted some other "creature comforts" that are easier to do now than later so i added a dozen wires or so for sensors and solenoids i knew im going to be using (E85,boost sol, oil press, misc sensor to be able to program and move for things like backpressures and the like). so now its an all inclusive harness that should in theory run everything engine and gauge wise. Other than an additional mechanical boost gauge i should end up with all sensors/controls through the ECU to a CanBus to the dash for everything to include speed, fuel, etc. Right now i have a RacePak dash but i may sell it and try to pickup an AEM canbus dash instead as i think its features match my goals better.
Nice harness when taking it apart

And a dozen extra wires for E85, oil press, boost sol, map change, datalog, 2-step, nitrous, etc. all the fun stuff.

And finished other than triming and terminating the plugs. This is where i finished last night so plan is to run this harness trminate what i can and then on to the fuel cell to finish fuel and wiring for first fire fingers crossed early next week.

Now thats a 20gal jegs fuel cell. Im going to be running twin internal 450s so i need to crack it open re-baffle and run the feeds and return to better locations. also with a 20gal cell and lowerd im running out of space under the bed for fittings etc. so i may shorten it a touch pending but im trying to have as much weight as i can back there for obvious reasons, lol.
