97 Accord- 5th Generation

So I posted elsewhere that these cars apparently need the Volo Fuel Saver chip. I imagine its that an EFIE device or MAF sensor enhancer does not work with the cars computer. I will be posting techniques and results as I work on my project.
I do need help on the firewall for the electrical wiring. I can't find any grommets that I can run wiring through though. Any help with that and anyone know anything special about the 5th gen accords that should be taken into consideration?
