Before cutting the OEM turn signal connectors off, just to make sure you like the new mirrors; cut the connector off of the new mirrors harness, strip back the insulation about a cm, then push these ends into the back of the OEM turn signal connectors. Test to make sure they are making good enough contact, then use a plastic wire tye to hold the wires in place.
Once you have decided you like the mirrors, then you can make the connection permanent.
