Hope the following is of use to people. I think this could be a supplement to the instructions for fitting a Honda Top Box.
What follows is an account of the fitting of the spoiler and brake light to my bike. I'm not a Honda mechanic, just a complete amateur. You would probably get better advice from a real Honda mechanic. If you blow up your bike, don't come crying to me!
Please note that I don't have this bike anymore, so the advice I can offer is limited.
A word document of this is available upon request, but I don't have a means of converting this into a PDF file. If anyone wishes to oblige, feel free.

Installation of the Honda rear spoiler with red lens
This article is in two parts. The first part covers fitting the spoiler to the Honda top box. The second part covers fitting the wiring harness to the bike to allow the use of the additional brake light.
This article is intended for ST1300 models fitted with the Honda top box.
First of all a warning. In order to fit the spoiler, you have to drill six holes in your top box. Please remember the old adage of ?measure twice, cut once? as drilling in the wrong place will leave a gaping hole in your top box. Please refer to the supplied instructions at all times, and if in doubt, contact your local dealer.
For the purpose of this article, left and right assume that the top box is fitted to the bike and you are facing forwards.
1. On the inside of the top box, locate the five dimples in the plastic which correspond with the centre of the spoiler mounting holes. Three of these are shown in pic 1. If you are not sure that you have the correct dimple, check the locations against the bolt holes on the spoiler.
2. Now you need to drill the holes. When drilling, make sure that the top box is places on a secure, but soft surface so you don?t scratch the paint. According to the instructions, the holes should be 9.5mm. You may wish to pilot the holes with a smaller drill bit first. Make sure you drill a clean hole, and smooth off any waste plastic afterwards.
3. If you are planning on wiring in the brake light, you need to drill a hole to pass the wires from the spoiler through into the top box. This hole sits 65mm to the left of the middle hole.
4. Make sure your top box is clean and dust free before fitting the spoiler. The instructions advise cleaning with isopropyl alcohol. I used furniture polish, for the pleasant lavender smell...
5. Now peel the adhesive backing from the spoiler and attach the spoiler, ensuring the wires for the brake light are passed through the correct hole. Insert the five sets of rubber washers, collars and 6mm bolts as per pic 2. Seal the hole that the wires go through with a flexible sealant or use a grommet to keep the box watertight.
If you are not planning on wiring in the brake light, there?s no need to read any further. Otherwise, read on.
The spoiler harness is purchased separate to the spoiler itself. It contains the bits you need to attach the spoiler brake light to the brakes on your bike. Conveniently, the colours of the wires on the spoiler harness match those on the bike.
1. Remove the rear mud guard. This is held on by four screws.
2. Now you need to remove one of the brake bulbs. I found that removing both the bulbs gave me more slack cable to work with. If this is the first time the bulbs have been removed, the holders will be stiff. As you are looking from the rear of the bulb, turn the holder counterclockwise about ? turn and carefully pull out. You will be left with something resembling pic 3.
3. You now need to cut the green/yellow and green wires from one of the bulbs. You are going to be fitting a plug and socket onto these wires, so give yourself some room to work ? you need to be able to get a crimping tool onto the wires.
4. You are supplied with a plug and a socket body that corresponds with the plug and socket on the end of the Y shaped spoiler harness. Taking care to observe the polarity of the wires, pins and plugs, crimp the pins onto the ends of the wires you cut in step 4.
5. Remove the seat and feed the spoiler harness down from the under-seat area, behind the left side of the tail light assembly. This is a bit of a fiddle, but there is plenty of room for the cable to pass. Plug in the accessory harness as shown in pic 4, replace the bulbs and re-install the rear mudguard. Before closing everything up, make sure that your brake lights still function. (Whether or not your bulbs function today, you can be guaranteed that one of them will still decide to blow tomorrow!)
6. Repeat after me... ?Measure twice, cut once. Measure twice, cut once...? In order to pass the cables into the top box, you have to drill a 16mm hole. (See pic 5) This should be placed 95mm from the top of the bottom part of the box (white arrow) , and 65mm left of the centre line. (Red arrow) Pilot the hole from the inside with a small (2-3mm) drill bit, then drill from the outside in using a 16mm hole saw or spade bit. Be sure to remove the rough edges from the hole.
7. The spoiler harness has a plug halfway down so you can remove the top box. Separate the harness at this point and pass the cable through the 16mm hole before filling the hole with the grommet that is stuck to the cable. Make sure the grommet fits evenly and is not pinched. Attach the bullet connectors on the end of the harness to the connectors of the stop light.
8. Using a 3mm drill bit, make holes to screw the cable clamps into. These should be drilled no more than 7mm deep, and should be located 55mm to the left of the centre line. Make sure that the cable will not be stretched when the box is opened. If you are not confident in your drilling abilities, the wires can be taped in place using electricians tape.
9. Fit the top box to the bike. Connect the two ends of the spoiler harness and pass them through the gap between the pillion seat and the passenger grab rail. Now test to make sure the spoiler light and the original brake lights still work. See pic 6
