SpeedFactory have redesigned their ecu jumper harnesses to use an ECU pin style connection at the back of the main plug. This new design is much more durable than the standard jumper harnesses that are available today on the market.

OBD0-to-OBD1 (multi-point) ecu jumper harness adapts a 92-95 OBD1 M/T VTEC & Non-VTEC ecu into an 88-91 Civic/CRX & 90-91 Integra chassis's. Includes a sub-harness for easy wiring for required OBD1 sensors (4-wire 02, IAB solenoid for B18C1 engine (if applicable), VTEC solenoid, VTEC pressure switch, and knock sensor.

Note: This harness is made for multi-point injected (4 injector) 88-91 Civic/CRX (HF/Si/EX) & all 90-91 Integra vehicles. 88-91 Civic/CRX STD & DX models require additional wiring to convert to multi-point injection before using this adapter.
OBD1 conversion also requires: OBD1 distributor, OBD1/2 4-wire 02 sensor, and OBD1 ECU.



OBD2a-to-OBD1 ecu jumper harness  allows you to use a 92-95 OBD1 M/T ECU into a 96-98 Civic, 96-99 Integra, 96-01 Prelude, and 96-03 Accord.

OBD2b-to-OBD1 ecu jumper harness allows you to use a 92-95 OBD1 M/T ECU into a 99-00 Civic and 00-01 Integra.
