LED Indicator Dash Wiring Modification
[FONT="]As many of you may have found out, we cannot simply remove the stock bulbs and replace them with [/FONT][FONT="]LED[/FONT][FONT="] indicators. The usual fix is to install load resistors in parallel with the LED’s. The problem stems from the fact that Aprilia elected to use a single turn indicator lamp. This bulb will tie the left and right circuits together and cause both indicators to flash. The following instructions will show an easy way to fix this problem. Minor electrical skills are a plus. I chose to solder all of my connections and used heat shrink tubing to protect any exposed wiring.
[/FONT] [FONT="]The following parts are required:
· 2 each IN4005 Diodes. Radio Shack p/n 276-1104 or Maplins
· 1 each Electronic [/FONT][FONT="]LED[/FONT][FONT="] Flasher Unit. I used p/n CF12ANL-01, purchased from Superbrightleds.com
Gain access to the rear connector of the instrument panel. You will need to remove the screen and dash cover at a minimum. I removed the headlight and upper cowling assembly to make things easier. It is a good idea to disconnect the battery before removing the 20-pin connector. Loosen the black zip ties and pull back the connector hood. Remove the black sheathing from the connector wire harness with a pair of scissors or equiv.
Locate the light blue (pin 16) and red (pin 17) wires. These wires will be cut, and the two diodes will be installed. Cut these wires approx. two inches back from the connector. Install the diodes on the ends that go into the harness, with the stripe end pointing away from the wire.
Wrap the opposite end of the diodes together and solder to the red wire that is sticking out of the connector (pin 17).
The light blue wire that is sticking out of the connector (pin 16) will be connected to the blue/green wire (pin 15). This will be the ground return for the indicator lamp.
Temporarily hook up the connector and reconnect the battery. It’s a good idea to test everything out before final assembly. If all is good, shrink down your heat shrink tubing.
I wrapped the wire harness back up using electrical tape. Re-secure the harness using the factory zip ties. I also used an extra one just to tidy things up. Note that I have also installed a HID headlight kit, so it may look different than yours.
