Default 99 TA cluster pinout?
Move if in wrong section but I am almost wrapped up with my MS3pro install and Was wondering if anyone here has the pinout for the gauge cluster?

True, the tach signal is sent to the cluster via class 2 serial data. If you need a tach signal your going to have to go to the pcm.

Are you sure it goes through the PCM? Does it go into the Body control module by any chance?

Yep should be pin 10 on the red connector. Its a white wire. It does not go to the bcm.

I’m very new to this so please bear with me. I have a 2001 fire bird that I’m doin an LS swap on I have found my tach signal (pin 10) how would I go about hooking that up to my stock gauge cluster? Would I use the serial data wire? Thanks
