Universal ZF 8HP Swap Harness, MaxxECU & CAN Bus TCU Compatible

The LSE9X Universal ZF 8HP Swap Harness is a fully terminated wiring solution designed to simplify the installation and control of a Gen 1 ZF 8HP automatic transmission in virtually any swap application.

Designed for ZF 8HP45, 8HP70, and 8HP90 transmissions, this harness supports compatible BMW, Jaguar, and Dodge/Chrysler Gen 1 8HP transmissions and is compatible with MaxxECU Mini, Sport, Race, and Pro ECUs when used for standalone 8HP transmission control.

The harness can also be used with other CAN bus ZF 8HP controllers that utilize the standard Gen 1 8HP pinout configuration.

Instead of building an 8HP wiring harness from scratch, sourcing individual connectors, or modifying an OEM harness, the LSE9X Universal 8HP Swap Harness provides a clean, fully terminated, serviceable solution ready to integrate into your swap.

Transmission Compatibility

Designed for Gen 1:

- ZF 8HP45

- ZF 8HP70

- ZF 8HP90

Compatible with applicable:

- BMW ZF 8HP transmissions

- Jaguar ZF 8HP transmissions

- Dodge / Chrysler / Mopar ZF 8HP transmissions

Controller Compatibility

Compatible with:

- MaxxECU Mini

- MaxxECU Sport

- MaxxECU Race

- MaxxECU Pro

- Other CAN bus 8HP controllers using the standard Gen 1 ZF 8HP pinout

When used with a MaxxECU, the ECU can be configured to provide standalone control of the ZF 8HP transmission.

BMW 10-Pin Shifter Connection Included

The harness includes the connection for the commonly used BMW 10-pin electronic shifter, making it easy to integrate a BMW shifter into your 8HP swap without building or re-pinning the shifter wiring from scratch.

The main harness uses a Deutsch DT 4-pin modular shifter breakout, allowing the shifter portion of the harness to be changed independently from the main transmission harness.

The standard harness includes the BMW 10-pin shifter connector.

A compatible Dodge/Chrysler shifter adapter pigtail can be used in place of the BMW connection without cutting or re-pinning the main harness.

This modular design gives you the flexibility to change shifter configurations later while keeping the main 8HP swap harness intact.
