Re-wiring Yanmar QM-15 instruments

Hi,

the instrument panel for my Yanmar QM-15 has gently failed. Too many heads and elbows in the motor bay have finally finished the original loom's connections. She has alternator, water temp, oil pressure and tacho with engine hours and one buzzer for all. I want to run new leads in a more ergomonic path to avoid the same problem. The runs will be less than 2m.

What is a good way to apply new connections to the sensor signal-out points?

They're all like single pins which accept a push-on socket but I haven't found one the same size, except on the wildly expensive replacement loom kit. Please excuse my lack of descriptive terminology..
