Thank you. Interesting site. I prefer referring to them as LEGACY equipment - makes me feel younger . I have an inquiry going, so we'll see what they say. At least they have a reasonable deal on the DIN connectors for the hydraulic valves - going to order a few. I see that they use the Deutsch connectors exclusively, so I asked if they have a Deutsch/Cannon adapter.I found a website that might be able to help us retrofit these antiquated attachments
it looks like he has many different options from new harnesses to wired and wireless remote systems
