hello 50 Chevy LS3. if you think that you have the ability to do the harness yourself, id say go for it. its not that hard. I can post pictures of mine when I get a chance. just to get an idea of what you have, take the harness and plug up the harness to the engine and see what pieces are missing. most of the connectors can bought on the net/web and added to the harness. trust me , its easier than you think. as a stand alone harness, all it needs is ground, ignition power, 12v+ constant power, reprogrammed pcm, and all the needed connectors plugged up and you are on the road. I bought a stock DBC harness off ebay, plugged, up all the connectors such as map sensors, MAF sensor, IAC, Injectors etc, added power and ground, and the LQ4 runs great. Of course you need fuel, tranny, tires and some other stuff but I'm sure you get the general idea. my harness has all the original wires. I didn't remove any wires. its bulky, but I only paid $67 for the harness. good luck. pm me if you need any help. ill help best I can. Clark.
