Igniton Switch wires questions -16 gauge vs 18 gauge wires Splice together OK ??

[OkieGuy]

My original ignition switch went bad so I ordered a replacement. I have a 2008 Bass Tracker 175 TXW with a Mercury Optimax 75 HP. The wires on the original one are clearly marked 16 gauge. The OEM number on the replacement is 87-88107A5 so I ordered a replacement marpac number 7-1155 that claims to be the same. The color of the wires are EXACTLY the same however the wires are 18 gauge. Has anyone run across this before? Would there be problems splicing the 18 gauge ignition switch wire into 16-gauge wire?
Thank you in advance.

It will be fine. Heat shrink and seal the connections tho. Or use the water proof connectors that you heat seal. Keep any moisture out.
