HA Motorsports ECU jumper/conversion harness for installing an OBD1 ECU into OBD0 Dual Point Fuel Injection (DPFI) chassis. Using this harness you can convert directly from OBD0 dpfi to OBD1 WITHOUT first doing an MPFI wiring conversion. All HA Motorsports ECU jumper harnesses are constructed using cross-linked automotive TXL wire that exceeds OEM specifications and is extremely durable. Uses all OEM ECU connectors for OE-like fitment. Designed and built right here at our facility in the USA!
For use on these vehicles:
- 88-91 Honda Civic DX/LX with manual transmission
- 88-91 Honda CRX DX/STD with manual transmission
Requires you to use your original 88-91 DPFI engine harness and modify it as needed to fit. The included pigtails provide your new injector wiring along with wiring for other components (VTEC solenoid, VTEC pressure switch, knock sensor, 4-wire O2 sensor, IAB solenoid, etc). Simply plug one end of the harness into your new OBD1 ECU, the other end into your stock OBD0 ECU connectors, then run the pigtail wires to the additional components.
NOTE: You MUST use an OBD1 or OBD2 distributor that fits onto your engine as OBD1 ECU's are not compatible with an OBD0 distributor's signals. All HA Motorsports ECU's, products, and services include a One Full-Year VIP Warranty
