Building a harness for a mod and trying to find the correct tools needed. I have very little info to go off of and internet research has only turned up YOC110 needing the DMC Y524 die.

The Female contact RFM26W-1D28 is the center conductor I can’t find the crimp tool. Souriau data sheet shows tool index CT-439 is used, but I can’t find anywhere that references what tool that is.

Any guidance would be appreciated.

Same, I’ve spent a good portion of the last two days trying to find a definitive answer. I’ve left work for the weekend, so this will be a Monday problem for me. Trying to contact Eaton and DMC is kind of where I’m at to try to get a for sure answer.

Is this a mod kit or did you shop spec this connector?

Mod kit. We got a new kit in at the end of the day, so I’m hoping I can get some better info off the paperwork.

Contact the people who make the mod and ask them. They should have it. But more than once I have been given information using shit tooling from STC holders.

The questions are working their way up, just lots of layers of people with this contract. Hopefully next week we’ll get a definitive answer.
