If you've been following me here a while, you may have heard me mention I work only on the 40-90 hp engines, and I do that as a hobby. The 40-90hp Honda engines I buy on the cheap as a hobby (dead/not running) are generally brought back to running like new/very good condition and sold for mad money. I only do 3-4 a year. There's a huge demand for them in that condition, and rarely do they last for a week when listed. Many/most guys want/need a set of controls with their new to them motors, and I try to accommodate with controls that I KNOW to be in good condition. I've learned that if my name is going on something it's going to be RIGHT to the best of my ability. Many of my customers turn into friends, and many times these friends have friends.....
Anyway, that control will work fine with a HONDA harness. The trolling control (I've never seen one with that feature) is very likely related a fuel injected motor. It's not something you'll use.
I mention that it will work with a Honda harness as I'm not absolutely sure what you have.
If you look at the pic in the ebay add, the ends that are directly above the motor, the one on the left (4 wire), and the one on the right (6 wire) are the important ones. You'll need a harness that will connect to those 2 sets of wires at minimum. Anything else that's there you will not likely use.
Further, have a look at the "related fitment" here. Note that they mention pre 97 40's and 50's. These are carbed motors that use the SAME controls and harness that you need - no "if's" to it.

Last, note there is a "watcher" on that ebay add. That's me. If that control is still there in a week, I'll move toward trying to buy it myself... -Al
