Proper Repair Harness for HVAC control fan

[tucsonjwt]

AC/Delco shows one repair harness for my 83 C20 HVAC fan switch. However, there are two replacement fan switches shown for this application. Does the one repair harness fit both switches? One switch has 4 pins (called manual A/C), and the other switch has 5 pins (called with bi-level, and I do have bi-level on the control), although one pin looks slightly recessed from the others in the switch. The repair harness does not list the 5 pin (bi level style) fan switch as being compatible with it.
Attached are pictures of the repair harness with 4 pin connector, along with the two styles of fan switches. Thanks.
