The Viper GC is the World's first mass produced commerical solution for the GameCube console, consisting of modchip, programmer and flexwire to connect the two together.
The Viper GC modchip comes with the programmer, wire install module w/reset switch clips and the flexwire.

The installation is simple, and consists of soldering only 4 wires and 1 bridge (bridge is optional if you own the BBA adapter). Total installation time will range between 15-60 minutes based on your level of experience; however, in our opinion even those new to soldering can accomplish the task relatively easily by following the detailed guide below.

PC Parallel Cable, useful, NOT required though. Some cables have problems, so be ready to unscrew the connector on the programmer and plug the bitch directly into the Parallel Port on the back of your computer.

It's easiest to start with the required solder bridge by melting a bit of solder between the 2 points circled in blue (the white text "Connect Together" points towards them). Next proceed to solder the 4 wires supplied from the Viper GC harness and if you have a revision C console notice that you will have to remove the main board to access the BOTTOM side to attach the Yellow wire.
If you have a Broad Band Adapter you can opt not to install the bridge, as the chip will work fine. This can be handy for disabling the modchip without having to unsolder anything (simply just unplug the Broad Band Adapter).
Continue on soldering all 4 wires from the Viper GC harness to the main board, and then after all connections are secure (verify them with a Digital Multi-Meter (DMM) if you have one using the Continuity setting) replace the heat sink making sure to leave the sticky thermal paste underneath it in-place.
NOTE: Do NOT jam your flexwire into the Viper GC chip's white/brown wire receptacle or you may DAMAGE it! Instead, pull the brown part out with your fingers, insert the flexwire in as shown, and then secure it closed by pushing in the brown part from both sides together simultaneously.
This is what happens when you’re not careful with the flexwire. Poor wire! If you would like to order a replacement wire you can do so by using either of these webpages.
This site has the original cable, but you must order $20 worth of products to have it sent. http://nz.farnell.com
Ultra-high quality 5ft replacement cable! Expensive, but worth it! http://www.digikey.com. Search for “MC14H-5-ND”
Finally, connect remaining blue wires (attached to the plugs) from the Viper GC harness to the corresponding plugs the upper-left corner, so that your lid sensor plugs look like the picture below. You will need to unplug the original wire harness from your unit, and then attach it to the Viper GC plug to bypass the sensor. Once the Viper GC module is active you will be able to open the lid undetected to swap for Import/LEGAL back-up game discs.
When reattaching the GameCube's back panel, be sure to route the flexwire through a slot in the back. This is the wire that gets hooked to your Viper GC Programmer when flashing the module with the latest Cobra BIOS.
