Overview

A tucked engine harness routes the engine wiring through the firewall instead of across the bay, and it is the cleanest way to finish a B-series or D-series build. It is also a working replacement: on a 25-plus-year-old chassis the original harness insulation gets brittle, and that is where intermittent fault codes, rough idle and misfires start. This AUXITO harness is the OBD2 version for B16, B18 and D16 engines, built to the shape of the stock routing so the connections land where the factory put them.

Vehicle fitment & specifications

Features

High-standard build
Made with stable performance and high reliability, to the same routing your car expects.

What it addresses

Durable
Made of superior material for long service life in the engine bay.

A note before you order

FAQ

What does "tucked" mean?
The harness routes through the firewall instead of across the engine bay, so the bay reads clean and the wiring is out of sight — a popular finish for show builds and swaps.

Which engines does it fit?
The B16, B18 and D16 series listed in the table above. Match your engine code, not just the model — the same chassis was offered with different engines.

Will it fix my fault codes and misfires?
If the cause is an aged, brittle harness — a common failure on these chassis — replacing it addresses it. If the codes come back, the fault is elsewhere and needs to be diagnosed before more parts are replaced.

Is this the OBD2 version?
Yes. This is the OBD2 harness for the applications listed above. Match your vehicle against the fitment table before ordering.

How do I confirm it fits my car?
Check your engine code (B16, B18 or D16) and your model and year against the fitment table, and compare the part number against your original harness.
