Dorman 4 wheel drive harness 600-600 question

[th3 shifty]

Anyone made the switch from the thermal actuator to the electric actuator and used the harness that Dorman has? The Dorman harness has 1 connector that will not plug into my chassis harness because it has round style connectors, my chassis harness has rectangle.. what did you guys do, that have done this upgrade?

Here’s the original GM bulletin with the instructions and part numbers for the varied years. Maybe it will help sourcing parts if the dorman product isn’t turn-key. Mine are both 98s, so I’ve no experience with the conversion.

Bringing this back, I bought a male 2 prong round connector to plug into the Dorman harness. The Dorman harness is using 1 black wire and 1 blue wire. The body harness/connector is 1 green wire and 1 black wire. Should I go blue to green and black to black? Having trouble finding wiring diagram for either of these.
If I follow typical GM color coding, black should always be ground, but I wanted to check here
