Check ebay and look for any 5 wire regulator/rectifier. Low and behold the GSXR (1100 in this case) from 01-03 is a five wire unit! It has 3 black wires, one black with red and one black with white.
To retrofit this to my 85 GS550E was easy....GS wiring was 3 yellows, one red and one black and white.
Black/White is ground on the RR and the GS
Black/Red is batter power on RR and the GS is Red
Black on the RR is stator and on the GS is Yellow
The connector was different in my case but the terminals were the same. I just removed the terminals from the connector and put them in the GS connector. The only difference was the ground wire which I changed the end to a bullet terminal since the GS is a 4 pin connector. I also ran a secondary ground from the battery (-) post to the RR mounting bolt.
It was a little bit bigger but that is easily cured with a hacksaw and file. I cute one corner off the RR (just the finned area) so it would fit in the original location.
The RR cost me $10 + 10.50 shipping on ebay for a total cost of 20.50! I just went to Mt St Helens and back with -0- issues!
Seems like a winner to me!
