I have a 1999 Yamaha F40TLRX that I bought on a used boat. I purchased a YDS Kit and it came with a 3-prong connector. I cannot find this matching connector anywhere on my motor. I have searched all over the internet trying to find out which connector on this motor is used for diagnostic hookup. The YDS provider said if I send him a picture of the port on my motor, he will see if he has the corrector cable. Problem is, I can't identify which port to use. Any assistance would be greatly appreciated!!! Thanks
