I made a few color coded test pins . They are .035 SS welding rod , with a Sub D female crimped on one end. Makes it a little easier to test the wire harness to double check the pin outs .
Great idea.
I also fabricated a test harness. Just two female pins with a pigtail.
I like your idea. I may add male pins to the opposite end of my test harness to check female D-subs too.
Thanks for the tip
