N52 & N54 Swap Harness Questions

If you plan on swapping an N52 or N54 engine into your e36, our harness adapters are the easiest way to go. Harnesses include the OBD2 diagnostic port, electronic accelerator pedal wiring, fuel pump relay wiring, CAS module wiring. oil pressure connector, coolant temperature connector, X60001 DME connector, and a custom CAN-bus emulator to simulate the missing E9x and E6x components.

All kits are made with high-temperature automotive grade wiring that resists oils, grease, and acids. Continuity is tested on every wire during construction. Harness adapters are wrapped in high-temperature expandable nylon sheathing to resist abrasion. All Kits come with easy-to-read instructions.

Check out the most commonly asked questions about our custom wiring harness adapters for the N52 & N54 Swap.

1) Q. What engine codes show up?
A. The normal codes that will possibly show up are: 2F4C, 2F4A, 2E8E, 2AAF, 2F71. The DME can be modified to have these codes suppressed, but it is not required.

3) Q. Can I check the oil level? 
A. Yes, our CAN-bus module allows for oil level checking. 

4) Q. Can you provide extra assistance with the swap, not wiring related?
