Electric Windshield Conversion ( ST1300 )

The 2004-2012, ST1300s all come with electric windshields. The 2003-2012, 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.

NOTE:  Over 300 conversions have been sold by CalSci.com to date.

These instructions are for people using the California Scientific wire harnesses instead of the Honda Front Sub-harness. 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 Sub-harness, 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 Sub-harness, 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 Sub-harness 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 Sub-harness to fit your existing main harness. You will have to remove the main Front Sub-harness 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 sub-harness.

WARNING: 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 whole point of the electric harness is to make use of the limit switches and the up/down relays. If you wire the relays incorrectly, you can accidentally bypass the relays and strip your little 5¢ / $350 gear. We have worked very hard to make certain this cannot happen to you, but you have to do your part: follow the directions carefully.

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.

  • Ratchet and 3" extension
  • 5mm Allen© wrench

Preparing the Motor Assembly: (about ½ hour)

1.  There are two blue wires coming out of the motor. About 1" back from the green connector, attach about 2" or masking tape to each wire. The green connector has an open edge, which lets you easily see the brass slide connector inside. This slide connector is connected to the striped wire. Write "down" on the piece of tape attached to this wire. Write "up" on the piece of tape attached to the other wire, the solid blue wire. Cut the green connector off the ends of them, leaving as much wire as possible on the motor. Discard the connector.

2.  Strip ¼" of the end of each motor wire. Attach a red ¼ inch female slide connector to each wire. These are the larger of the four red female slide connectors.

3.  There are two black plastic wire conduits on one side of the motor assembly coming off the limit switches. Each plastic wire conduit contains a black and a red wire. The four wires end in a white connector. When the motor assembly is installed in your bike, the motor will be down and the windshield tracks will go up. About 1" back from the white connector, attach about 2" of masking tape to each of the black plastic wire conduits. Write "up" on the tape attached to the conduit which goes to the limit switch at the top of the windshield track. Write "down" on the tape attached to the conduit which goes to the limit switch at the bottom of the windshield track. Cut the white connector off, leaving as much wire as possible in the conduits. Discard the connector.

4.  There is a tie wrap attaching the two black plastic conduits to the motor frame. Remove the tie wrap entirely and discard it.

5.  Strip ½" of each of the four wires. Fold the exposed wire over so that it is double thickness and ¼" long.Attach a red .187" female slide connector to each black wire. These are the smaller of the four red female slide connectors.Attach a pink fully insulated male slide connector to each red wire.

6.  Take one of the blue relays and write "up" on it. Write "down" on the other relay. The relays are identical, it doesn't matter at this point which you pick.

7.  Attach the green wire harness to the two relays. Slide the red connector onto the middle upper tab on the "up" relay. Slide the nearest blue connector onto the right upper tab on the "up" relay. Slide the next blue connector onto the middle upper tab of the "down" relay. Slide the last blue connector onto the right upper tab of the "down" relay.

8.  Attach the red wire harness to the two relays. Leave the pink fully insulated connector hang for a moment. Attach the next blue connector to the middle tap on the "up" relay. Attach the last blue connector to the middle tab on the "down" relay.

9.  Attach the solid blue motor wire labeled "up" to the lowest tab on the "up" relay.

10. Attach the blue striped motor wire labeled "down" to the "down" relay.

11. Attach the black wire from the black conduit labeled "up" to the upper left hand tab on the "up" relay.

12. Attach the black wire from the black conduit labeled "down" to the upper left hand tab on the "down" relay.

13. Both relays should have connections made to all five of their tabs now; there should be no open tabs.

14. Cut ¾" off the open end of each relay suspension rubber boot.

15. Attach the red wire coming from the switch to the pink fully insulated open connector on the red wire harness.

16. Attach the black wire coming from the switch to the pink fully insulated open connector on the red wire coming from the "up" limit switch.

17. Attach the blue wire coming from the switch to the pink fully insulated open connector on the red wire coming from the "down" limit switch.
