2000S 986 to 996 cluster swap

[Luckyman01]

First off, I have reviewed the site search results and Wayne's 101 projects prior to posting, so off we go.

While I do understand I will have to replace oil pressure sender and run a wire, what gauged wire?

I do understand that year and model of 996 gauge matter, in my case I need a 2000 996 gauge from a 6 speed Cabriolet from a C2 car.

What I am unclear on is the need to reprogram my 986. I read that you may or may not need to reprogram?

If that part is true, can I ensure that the used cluster would be compatible without needing any programming.
