Hi
A few of my Greddy gauges started to flicka and I have found the issue to be the poor contact in the yellow plugs. Does anybody know where to get the metal crimp terminals from, pics attached thanks in advance mark

 

Another pic of connector

 

Have you tried to just get another harness from Greddy?.
Ebay may have the odds and ends also to help you.

I know I had a harness that I sold a while back that had that connector,but that isn't what you want to hear..sorry.
That's a damn small connector too so it is a pain in the keester.

 

That would be the last resort. I'm looking at computer connectors to see if the size of them are the same, like you say it is tiny but hopefully something will show up
