Hello Greenkeys members,

I recently came across this YouTube video
(https://youtu.be/YbyksG-lj60?si=6pfCYF4mEFMvSDFg) and received wiring
details from Erik, the operator of the channel, for connecting to J2
(power input) on the AN/UGC-74B(V)3, as shown in the attached photo.

For AC 110–120 volts:
Jump B, D, L and A, C, J, and apply voltage to M and K, with E as
chassis ground.

For 28 volts DC:
Jump J, G and L, F, and connect M to +DC and K to –DC.

I also received information regarding the J1 data connector wiring.
Now, I’m trying to locate or identify the correct mating connectors
for both J2 (power) and J1 (data).

If anyone here has specifications, pinouts, surplus parts, or
suggestions on where I might find compatible connectors for the
AN/UGC-74B(V)3, I would be extremely grateful.

Thank you in advance for any help or guidance you can offer.

73,
Youngluck
