Switching to MPFI using original TBI harness...
My car previously had a 305 TBI, this has changed to a 400sb running carb currently until I can get EFI setup. I would purchase the Holley 950 system but I already have a harness from when the car was TBI. Is there a way to match the components together from the kit w/o the harness for less money? Or will my stock harness not help me out?

Nice 'Bird. I don't think you can use your old harness without a lot of repinning. Holley does sell a 950 kit for TPI cars & it comes with a harness for around $850. You would have to get a TPI setup if you don't already have one.
