Hello I am new here and new to boating. I just bought a couple of months ago a 2001 Larson 21 feet deck boat with an outboard configuration. The boat is from the auction and the boat was sold as his, the engine was stolen before I bought the boat so the cable and harness were cut. At that same auction I bought a 1998 johnson 200 hp outboard engine.

I am now trying to merge the two but I am having issues with finding the right cables but most importantly it is the wiring harness that is giving me trouble. On the boat side I have 15 wires. I have nost figured out like the trims , power , ground, rpm and such but I have 4 that I can't find info on ; two brown, a brown and black and a white with yellow.

Can someone pleas help me?
Thank you very much!

Look at the control box. Should have a logo or some ID on it as to Merc, Honda, etc. Harnesses are not plug & play between engine manufacturers.
