I am writing this for others that may look at this and be intimidated by the wiring instructions. I really appreciate all that have contributed to this thread as each post has helped me get to the point where I finally bit the bullet and did the deed. I will add some of my insights and pictures that may help others.
I had previously installed the vacuum type of cruise control so I was not worried about the mechanical aspect. The wiring was my worry.
First there are wires on both the cruise control unit (CC) and the Goldwing switch (GWS) that are not used. These I wrapped carefully with electrical tape, some I cut shorter for convenience. The Centrodyne divider had all wires connected. In the next few paragraphs I will try to list each wire from each unit and where it attaches.
I will use the following abbreviations for colors.
Black- Bl
Blue- Bu
Brown- Br
White- W
Red- R
Yellow- Y
Gray- Gy
Green- G
Violet- V
Sky Blue- SBu
Light Green- LtG
Orange- O
Light Blue- LtBu
Pink- P
CC (cruise control unit)
Gy- to W on Centrodyne divider
Bu- to Bu on the left coil or Bu/Y on the right coil
Br- to a 12v switched + from the Quartet harness (Q) or other (+) source
Bl- to ground in Q harness or other (-) source
V- to brake switch cold, G/Y from 9 pin connector from right handlebar switch
R/Br- to Bl/G from GW switch
G- to W/Y from GW switch
Y- to W/Bu from GW switch
O- not used
LtG- not used
J Auxiliary speed connector- not used
K 4 pin switch cut off and not used with GW switch
L 2 pin connector- not used
GW switch ( Goldwing switch- #35130-MCA-A21 with back light)
W- to Y/Bl in 9 pin connector
Bl/W- to Bl in 9 pin connector
G/Y- to G/Y in 9 pin connector, this is the brake cold wire
W/G- to Y/G in 9 pin
Br/R- to Bl/R in 9 pin
Y/R- to Y/R in 9 pin
Bu/W- to Bu/W in 9 pin
Bl/G- to CC- R/Br
W/Y to CC- G
W/Bu- CC- Y
Bl/Y- to (+) from Q (switched)
LtBu/Bl- to (+) from Q (switched)
G-to gound (-) from Q
Y/W- not used, available for another circuit on the reverse on/off switch
Bl/R- not used, available for another circuit on the reverse on/off switch
Br- not used, available for another circuit on the reverse on/off switch
Bl/Br- not used, available for another circuit on the reverse on/off switch
G/W – not used
Other end near GW switch
W/G- attached to brake switch
G/Y- attached to brake switch
Bl/Y- not used, capped off
G/W- not used, capped off
Centrodyne Unit
W- to Gy from CC
G- to P/G found at the 27 pin connector on left of bike under gas tank area
R- to (+) in Q harness
Bl- to (-) in Q harness
I will attach a copy of my wiring diagram.
All (+) sources should be switched, in other words no on when the key is off and each should have an in line fuse. I used the Quartet harness for most of mine.
My Centrodyne divider is set at divide by 2 and high gain and I did not clip off the #8 capacitor, the newer units may not need these settings.
My throttle grip needed to be cut off by about ? inch as the GW switch is wider.
