The SIR coil connector has letter designators for each of the wires as follows:
A - Grey
B -
C - Light Green
D - Brown
E - Pink w/Black stripe
F -
G -
H - Dark Green w/White stripe
J - Tan
K - Black
The connector to the radio controls is not labeled, but looking at it from the top/front of the steering wheel the wire colors are: Black, Brown, Pink w/Black stripe, and Light Green. Your Cruise control wires should be (not in order) Grey, Brown, Pink w/Blk, Dark Green w/Wht, and Black.
I don't know how the controls work with both sharing three common wires but it does????
