This 4-pin Extension Harness for Haltech Nexus R5 VCU Connector (E) is a build-to-length harness and will allow you to relocate the VCU beyond Haltech's engine harness length limitation.
All wires in this connector are 12 AWG in size.
Fully compatible with the new Nexus Software Programmer (NSP) Calibration Software.
Each build-to-length harness is custom-made to your selected length. We are unable to accept returns on custom-length harnesses.
