[Mrmerlin]

Hi I have a 01 GS 1150 and I cant seem to find where the co pot is , I am trying to put in a potentiometer, to adjust the fuel injection can anyone give me some Ideas as to where this part connects the potentiometer has a 3 prong connector so i need to find a 3 prong female connector.
Also where is the cat code plug I looked under the fuse panel and there are 2 yellow relays and one has 2 prongs and the other one has 4 , all the other relays are black........ any one know what the story is????? Thanks..........Stan
