I would just like to say how delighted I am with your large windscreen I purchased recently. It really has made, for me, riding
the ST1300 a much more enjoyable experience. Gone is the need to wear ear-plugs, as this screen has removed most of the wind-
noise. That has been a huge benefit to me. Gone is the buffeting by the wind on my arms and helmet, and even though I have the
handle bar risers fitted, I do not get wet wrists or arms when riding in wet weather. With the under-mirror deflectors, it has
also removed the wind buffeting for my pillion (my wife), which obviously has increased her enjoyment in riding the ST1300.
The 2004 ST1300s all come with electric windshields. The 2003 ST1300 standard model is the only ST1300 which will ever be produced without an electric windshield. Because of this, if you do not convert your 2003 bike, I predict you will take a beating when trying to sell it. California Scientific makes an accessory wire harness and modifies the ABS style switch set to make this conversion electrically easy, and mechanically only a bit tedious.
These instructions are for people using the California Scientific wire harnesses instead of the Honda Front Subharness. If you're using the California Scientific wiring harnesses, you do not need a Service Manual, all the pictures and instructions are on this web page, including .pdf's of the relevant service manual pages.
These instructions are mechanically correct no matter how you wish to power up your system. However, if you are using the Honda Front Subharness, you should not follow any of the electrical instructions below. Don't cut off any connectors, don't remove the limit switch tie wrap, don't strip the accessory harness wires or install t-taps.
If you choose to use the Honda ABS Front Subharness, you're on your own. You'll have to figure out how to get it attached to your existing wire harness. I've never done it this way, so don't ask me for help. The Honda Front Subharness is made to connect to the ST1300A main wiring harness, which you do not have. This is why the dealer says you need a completely new wiring harness for your bike, about $1000 installed. Otherwise, you'll need to modify the Front Subharness to fit your existing main harness. You will have to remove the main Front Subharness connector, and get a different connector and wire it up appropriately. Good luck. You'll also have to modify your ABS style switch set, as this plugs into the main wire harness, not the front subharness.
The accessory wire harness is a Honda optional part required to install the Honda heated grips and the Honda radio. We will use it to supply power to the motor. The up/down relays are to make sure the power is turned off when the shield maxes out. Without them, you will strip a little 5¢ plastic gear, which will require you to buy an entire new $350 adjuster assembly. The relay suspensions are rubber boots to hold the relays in place and protect them from the elements.

Here's a copy of the pages in the Honda Service Manual that deal with removing and replacing the fairing. You can download them (about 6.5MB) and print them out for pictures and extra instructions. This job has been done using only the instructions below. Printing out these pages is optional. Thanks to Michael Maynard for scanning them in for me.
