Ok Heres My Bogle... I have an 89 2.8 MPFI FireBird. I am Swapping in a Carbed L98(I know Rip on me if ya want to) I want to keep my Stock Gauge cluster If i can. Im also swapping in an older TH350 Tranny So I dont know If my Speedo Will Still work. I also dont know how much of the existing wiring harness I can remove without messing up my Gauges.... Im trying to clean things up under the hood as much as possible.


Any Help Will Greatly Be Appreciated...

If my gauges Wont work with the swap What Will I need??

You will probably need some new stuff for the speedo but all the other guages should work if you use the right sensors - ie coolant, voltage, oil pressure etc.
