Looking for help identifying a connector

Hi, I’m installing a blind-spot sensor kit on my truck. They kit was designed for a car, so the wiring harness is a bit too short. I want to try to make some extension cables before I cut into the existing harness, but am having trouble identifying the connectors. They’re cylindrical and quite deep. The barrel is as thin as or thinner than a pencil. I need both the male and female. 3 pics attached. TIA
