Vortec 5.3 install on my 84 C10

Pulled the wiring harness, trimming it up. Actually not that daunting of a task with LT1swap.com and Cpt Kaos.

I'm almost at that point on my other project.  just want to finish the paint first.  I'm hoping that the wiring on mine will go as smooth as everything else.

Got the harness reloomed and reinstalled into my truck. I put my ECU above the glove box, near where the original "ECU" was. A little concerned if the speaker magnet will hurt it. I also started pulling stock wires inside the cab, removing all wires that are no longer needed.

I reloomed my harness just like LT1swap says to but I'm a little confused on one thing. I thought the C1 pin and such would be eliminated during this. But i still have quite a few wires coming from it.

This is what i'm talking about. Any one know anything about this? I have heard that the pink wires are injector wires.

on the 14th little picture it says to label your pink wires as you cut them from the connector.

this should help...

Thank you, i didn't see that. It just says bundle the pink wires like the fuel relay? Do i provide power to all of them? Also, how do i figure out the exacts of all these pink wires?

OH OH OH, found it! http://lt1swap.com/vortec_truck_pinouts/1999.htm This means i'm not quite done yet, I'll finish up this wiring tomorrow

just remember that the "pink" wires are key on powered and "orange" are battery powered.

GOT IT, all soldered up! turned the key, heard the pump for 2 seconds, turned further and vroom! purring like a kitten on old gas. lol

Thanks guys.
I am a little lost on electrical now though. I have tail lights (night running), blinkers (i be it, slow flashes) and brake lights but I cant get my headlights to work at all. I am running a hot wire from the battery to the main dist. block on the fire wall. So i get AC, radio, so on so forth. Any ideas?

Working on building a all metal dash today. Mocking it up with poster board. still a rough layout. Going to weld it up outside the cab then rivet it to a frame inside the cab. That way i can pull it if i need to do work on the truck.

very cool idea, but what's wrong with your factory dash?
