Aftermarket Tach in 98 trans am

Where does the signal wire go for an aftermarket tachometer in a 98 trans am?

Re: Aftermarket Tach in 98 trans am

It's my buddy's car and he likes the way it looks. We got it installed yesterday, it is the white wire going into the pcm, pin 35, and has to be set to 4 cylinder mode.

Go to installuniversity.com or ls1howto.com and see how the shift light is wired. You'll tap into the same wire.
