[R-390] PTO extender cables

[Barry]

Anyone have a source for connectors to make some extension cables for the
PTO?  I want to do some linearity checks and would like to do it outside the
frame on the bench.  I realize I can get a set of connectors from Fair
Radio, but they include a lot of connectors I don't really need.  The
harnesses from ATC might work, but I'd still need the male connector.

Any ideas?

Thanks,
