[bbds]

Hi guys,
just need abit of advice i have an 1996 civic h series currently using a ek4 ecu.
Just recently purchase a jdm p13 h22 ecu, just wanted to know which harness i would need to purchase?

Any opinions would be great also

your EK4 is OBDIIa and if the P13 is OBDI you need an OBDIIa to OBDI convertion harness
