I have a question : Did BRP change the wire location on same or differnt color plugs from different model years? For example I have a 1970 85hp and a 1973 115hp with yellow plugs, with the same wires but looks like they might have placed them in different locations within the plug, is that possible? I'm just curious. They might have done that just so you dont exchange wire harness and to save money and charge greater cost, even to save money in cost of operations.
