Question:
Is Item # 18156 compatible with Item # C57674 and/or Item # C57672. If not, it compatible with any 4 way to 7 way adaptors?

Both Curt wiring harnesses, part # C57674 or # C57672, will fit with the Mounting Box # 18156. The only problem is that these also come with 4-Way connectors as well which the mounting box doesn't have provisions for.
I recommend using the Curt Wiring # C57674 along with the No-Drill Mount Bracket # C57202 which uses a similar strap to mount around the crossbar as the mounting box does. The difference in this case is that the bracket that comes with the Curt wiring is designed to accommodate the 4-Way connector as well.
