Looking to get a racepak sportsman for my 4th gen camaro. Anyone know where to tap to get a tach signal? Would I use the #10 pin on the red PCM plug and set up racepak as 4 cyl? Thanks in advance.

Good question, I would assume there is a tach input into the factory gauge cluster?

yes.... pin 10 on red connector, and set it to 4cylinder
stock pcm outputs a standard tach signal, but as a 4 cylinder(GM does stupid things sometimes)
