Datsun 280z l28et Godzilla raceworks megasquirt plug and play part 2 (engine started )

In this video I got the engine to fire up I still need to tune a couple things. And re-route a few things to my liking but overall this is a great product but could use some help because I’ve notice that after my installation of the product not my stock tach doesn’t work.
I’m not sure how to go about this and what’s its fix but I’ll be doing some research and once I figure that out I’ll make a video.
I’ll. Also make a video of how I installed my wideband
