This jumper harness was designed to make installing a Honda F-Series engine into a late-model BMW E30 (1989+) easier.
You only need to wire in one standard relay, allowing the ECU to control your radiator fan.
We need to know the year of your E30 to make sure you receive the correct harness.
Requires a stock or aftermarket S2000 engine harness.
Available Options:
- 88–89
- 90–91
For questions or to confirm your vehicle year, email 625inco@gmail.com.
