Just bought a Merc 525SC. My previous motor did not have an engine plug so I have a cluster of wires.

The 525 has the female plug for the engine harness. It's a 10 pin plug. Wondering if anyone has a part # for the plug, or a generic 10 pin that will fit that I can just wire up myself.

There also is a female plug coming from the thunderbolt ignition that I do not know what to wire to.

Any tips or suggestions to simplify install would be great. Thanks

​​​​Thanks but I need the side with the prongs that plugs into the engine side.

Ebay always has a bunch search merc 10 pin harness, you are looking for the boat side. You can play splice and dice or just get one long enough to tun to the dash and redo it,its pretty simple,

this should help....

Scroll down the page a lil bit

thanks! That plug has 9 prongs, Im guessing it should still plug in and there's one hole that's not essential.

Thank you!

9 and 10 plug are basically the same
