Troubleshooting & FAQ

Q: How do I know if this harness will work with my trim motor?
A: This harness is specifically designed to convert a 3-wire tilt and trim motor system to a 2-wire system. If your Mercury engine falls within the 65-125 HP range (1994-2006) and you need to make this conversion, this part is compatible.

Q: Will this fit my 1995 Mercury 90 HP outboard?
A: Yes, this harness is listed as compatible with the Mercury 90 HP (3-cylinder) 2-Stroke engine models from 1994 through 2006. Please consult the compatibility table to be certain.

Q: What parts are included in this kit? Are relays included?
A: Yes, this is a complete kit. It includes the main wiring harness, one 30A fuse, and two 12V 20A/30A relays. You will not need to purchase these components separately.

Q: My trim motor is not working. Will this fix it?
A: This harness assembly resolves issues related to faulty wiring, bad relays, or a blown fuse. If the trim motor itself is defective, replacing the harness will not solve the problem. Test the motor independently if possible.
