1990 454SS tach
I have a 91 tach dash to put in my 1990 SS truck. I have done these before but lost the repin info. I have been all over web sites looking for that repin info but cannot find it. Anyone remember?
Thanks Scott |

To use a 1991 cluster in a 1990 truck, you have to move B15 to B11, A11 to A10, and A10 to A9.

Re: 1990 454SS tach
Thank you very much. Which pin will serve the new lead from the tach?
Thanks Scott |

You're welcome!
B11 Signal to the tachometer.

Re: 1990 454SS tach
ChevyTech,
So your saying that the B15 connector that I'm going to move to B11 is a tach signal? I didn't think the 90 truck had an existing tach lead since it never had a tach? Thanks Scott |

I have never done this swap and my notes were from other members input from the boards. If I can find some free time in the next few days I will do some research and post my findings here.

Re: 1990 454SS tach
I remember that there was an empty terminal wire right at the top of the coil. Used to be able to hook up a dwell tach to read the rpms working under the hood during tune-uos.

Re: 1990 454SS tach
Works great. B15 on the dash plug was the tach signal port. Extra wire coming off the coil to feed the tach was ea
sy. I hope this thread stays alive so that others can find it and easily do this task. Thanks for all the help. Scott |

Glad it worked out well for you. Thanks for the update. The thread should be around for people to find with a search.
