OBD1 Engine Harness – Honda B / D / H-Series | Engine Only Kit | VTI StreetSpec

VTI StreetSpec OBD1 Engine Only Kit – Honda B / D / H-Series

All the quality of the VTI StreetSpec platform — without the chassis interface. The Engine Only Kit is built for custom chassis builds, non-standard swaps, or builders who already have their chassis wiring sorted and just need a world-class engine harness with proper power and ground sorted.

Built in-house using TXL automotive-grade wire, finished in FR expandable loom and SCL-style heat shrink. No Tessa tape. No budget shortcuts. Ships ready to drop onto your engine.
