Modify your own Standalone LS Wiring Harness into an LS Swap Chevy GMC OBS Truck

Part 23: The Chevy OBS Project Truck needs wiring! What are your choices?: 1) Buy a new LS swap harness, 2) Send your existing harness off to someone else to modify or 3) Do the work yourself. The first 2 options are great options to have, but, they also come with a higher price tag. I chose to go with option 3.
There are a number of videos out there that cover the main points of the process. I decided to make this more general and what I did specifically for my swap into a 1991 Chevy OBS. However, the tips and things I did are applicable to most any other project vehicle. My project was specifically needing to be for 1) Drive by wire, 2) include a 1 wire sanden a/c compressor, 3) cruise control to work, 4) 3 wire temp sensor, and 5) No electric fans, but with wiring to install in the future if I change my mind.

While this process looks very intimidating, it is not so bad. Keep an eye on your overall project, but focus on smaller parts so it does not become overwhelming until you get familiar with the process. It always takes more time (at least for me) than most videos actually show. Take your time, relax, get comfortable and get a beverage. If I can do this, I promise you can do it as well. BUT before you just jump in, do your research about each part you can think of. Have some answers before you start cutting. You will need a soldering iron/gun and solder, heat gun or other way to shrink the heat shrink (always use marine heat shrink, it seals on the inside as well to keep moisture out), wire cutters, ice pick or very small screw driver for pin removal, an ohm meter is very handy to have, masking tape, sharpee, electrical tape and or cloth tape. If you get all this together before you begin, you will have fewer interruptions as you work. GOOD LUCK AND HAVE FUN!!
