My LH rear light was intermittent and it turns out moving the connector a little makes or breaks the connection. My rear light circuit boards have gold plated fingers so the problem is the OEM connector. I dipped the connector in TARNEX and then blew it out and dipped it in solvent and blew it out. Still was a little intermittent. I then bent the pins in so it made a tighter fit and all that improved the problem but I still can see a slight flash (I have LEDs) moving the connector a little.
Has anyone found replacement pins? I would think not since these are RISK connectors. I think I will look at replacing them with a modern connector pair. Just solder the wires on the male side to the circuit board.

I believed I saw a replacement connector on the DPI website the other day.

I need to find some other things to order from DPI else shipping is $25.

Found the problem. Not sure if this was done at factory but it looks like someone could not use a crimper on that red/black wire. It does look as old as the good crimped pins.
Do the replacements from DPI and Dgo require a special crimper?
I will Probably just solder this bad crimp.

I just used a normal crimper? YMMV

I fixed that bad "crimp". I was able to open the attempted crimp, cleaned the inside by scratching with exacto. Stripped a new part of the wire, cleaned it with 220 grit and tinned the wire. Then I just rolled the crimp since my crimpers would not work with those terminals. Soldered the result. Now no intermittent.
I think you would need a crimper that has the tooling on the end of the jaws to clear the spring end.
