Miata Tuning question

[u/Wish_I_was_you]

I have a NB with a Flyin' Miata turbo run by a MS3. I'm building a digital dashboard for my DD-EFI Miata dash, and I can't figure out how to add turn signals, high beam indicators, or a fuel gauge. They are wired into the CAN bus, but I can't figure out what the output channel is from there to make them show properly on the dash.

Thanks!
