As long as they're both mpfi any obd0 d series harness will be plug and play I believe

X2. If the crx is dpfi you will have to change the cabin harness.
If you Trynna change your dpfi harness to mpfi you can find a do it yourself on honda-tech

ya if your converting to mpfi you need to wire in two more injectors and a resistor box if your still running dpfi i would convert immediately dpfi is garbage lol

Anyone on here do this conversion and how much would they charge

[91efhatch]

Just the wiring or swap the manifolds over as well?

[cayeyda9]

Yes both

I know a couple ef experts that could possibly help you out not sure if they have that parts for it I don't think they do d series anymore but ill ask

[cayeyda9]

Thanks I would greatly appreciate it atleast how much they would charge if I find the parts and also if they do auto to manual swaps
