Step 2: A+B method.
If you have a Japanese Saturn you cannot use this method, move onto step 3 for instructions. To do the A+B method you simply solder signal wire A to point B on the Modchip. Alternativly you can completely remove the signal wire and create a solder bridge between the two points. The solder bridge is probably a better way to go because it just eliminates possible future problems. Its important to note that on Sanyo Saturns the A+B method does not always work. I recommend trying this method first though, read step 3 for more information.
Step 3: Alternative to A+B method.
If you have done the A+B method, then you can skip over this step however it may not be possible to use the A+B method with all Sanyo Saturns. The following method is to my knowledge fairly untested on US and Euro consoles. It will not damage your system but there is not a guarantee it will work. You need to remove the CD drive from the console (simply disconnect any power inputs and slide it off the posts) and turn it upside down. Locate the Sanyo chip and trace pin 7 to a place that has easy access to solder Signal wire A to.
Again this method is not documented well, and I currently do not have any pictures to help you out. Its worth a try if the A+B method doesnt work.
