Muti-function tach upgrade/harness adapter

[chinz67]

I have a multi-function tach (6Y5-83500-03-00) I'm replacing with a t-82 which has the red-yellow-green indicators / squares across the bottom. I bought it new and need a part number for the harness adapter to convert from round connectors to the new style square connectors. Please help!!!
My engine is a 1993 C115TLRR. I'm frustrated!

Not gonna be any help to you just wanted to let you know I am facing the same frustrations. I have a 2004 250 HPDI and I have found the newer "true" digital gauges won't work with my motor. Have to find digital gauges based on analog signal. They are available but hard to find. Hope you have the right style gauge. Not sure if you were aware of these differences. Just thought I would pass on what I have learned so far
