Re: Johnson control box - 3 pin connector
BRP is Bombardier Recreational Products, successor to OMC after the bankruptcy.
They have been kind enough to post parts manuals for most of the outboards since 1968.
Unfortunately, they don't sell parts at retail. But,you can get the part numbers and that is a huge help.
Copy the link to your browser, without the quotation marks:

If you wish, you can download the parts lists to Excel and print the parts diagram, so that you will have a hard copy of your parts manual.
