Default Question about a wiring harness

So I started to work on my wiring harness. It's from a 99 chevy silverado with a 5.3. I pulled the motor myself and i had to cut some wires and i hope you guy can help me figure out what they go to. I also included a picture of where it is in the harness. I'm trying to make a stand alone harness
There are 3 pink wires, 5 solid black wires, 1 yellow wire, 1 purple wire, 1 black with white line, and 1 tan wire

I can't really see what connectors you have in pic, Pink wires are power wires, Black wires are grounds get a multi meter and trace back to connector the other wires probably connect to pcm www.lt1swap.com

Those are the injector wires and the big plug for the coils and a ground of course.

All those wires will have to got to pcm lt1swap has pinouts for most harnesses. Multi meter will be your best friend for this, GL
