❓ FAQs:

Q: Is this the same harness that comes with the Nexus S3 wire-in kit?
A: Yes. It’s the 2.5m universal harness sold with the Nexus S3 in Haltech’s HT-213200 kit, sold here on its own.

Q: Will it plug into my factory engine harness?
A: No. It’s a universal harness. For a factory plug-in fit, look at Haltech’s plug ‘n’ play adapter harnesses.
