I finished the installation of the Rostra cruise control using the Gold Wing backlit control. A big thanks to altest1300 for his great instructions. He used the non-backlit control in his instructions. With the backlit control, some of the wire colors have changed from Al’s instructions.
Here are the updated wire colors and parts:
Gold Wing backlit control #35130-MCA-A21 from a 2005 Gold Wing. $137.85 from Hondaparts online.
Hook up 12V with a 4 amp fuse to the Black w/Yellow wire on the Gold Wing switch.
The Black w/Green wire hooks up to the Rostra Red/Brown wire.
The White w/Yellow wire hooks up to the Dark Green Rostra wire.
The White w/Blue wire hooks up to the Yellow Rostra Wire.
The Brown Rostra wire needs to be hooked up to a 10 amp switched circuit. I used a relay that is turned on by power from the Quartet Harness.
In the dipswitch settings, Al’s instructions state that switch 12 is in the “ON” position. The backlit switch is an open circuit switch, so number 12 needs to be in the OFF position.
The Rostra Blue Tach wire gets hooked up to the Blue w/Yellow coil wire. I just made a pig tale so I did not have to cut the coil wire.
To get the backlights to work, I ran switch power from the Quartet harness and hooked it up to the Light Green w/Black wire. This wire also had red squares on it. The solid dark green wire needs to be grounded. Now the backlights will work when the key is on.
If you want to use the Reverse Shift Switch to turn on and off Aux lights, you will use the Yellow w/White and Brown w/Green squares. I ran keyed power from the Quartet Harness to the Yellow/white and hooked the Brown wire to my Moto light relay.
If you have any LED’s for brake lights, you will need to put a relay in to get a good ground for the Rostra Violet wire. Wires to hook up to the relay: #85 to brake negative (+12v when brake is pressed), #86 to ground, #87 not used, 87A Rostra violet wire, #30 to ground.
Below is a photo of what the Gold Wing switch looks like with the lights on.
