Elite 1000/1500 Maz 13B Term S6-8 CAS Harn Only No Sub harn

Overview

The Elite 1000/1500 Mazda 13B Terminating CAS Harness delivers plug-and-play wiring between your rotary's crank angle sensor and Haltech ECU. Purpose-built for S6, S7, and S8 rotary conversions, this harness eliminates complex sensor wiring whilst maintaining the precise timing signals critical for rotary engine management.

Technical Specifications

• Part Number: HT-130334
• Application: Mazda 13B S6, S7, S8 rotary engines
• ECU Compatibility: Elite 1000, Elite 1500
• Connector Type: Terminating harness (no sub-harness required)
• Sensor Interface: Mazda CAS (Crank Angle Sensor)

Why You Need This

Rotary engine swaps demand absolute precision in crank angle sensor wiring — get it wrong and you'll face erratic timing, misfires, or complete engine failure. The Mazda 13B's CAS system differs significantly from piston engine trigger patterns, requiring specific signal conditioning and proper earth paths. Generic wiring or botched sensor connections are amongst the most common failures we see in rotary EFI conversions, often leading to expensive engine damage.

This terminating harness solves the complexity by providing factory-correct connections between your 13B's original CAS and the Elite ECU's trigger inputs. Whether you're dropping a 13B into an RX-7, fitting one in a kit car, or completing a rotary-powered drift build, this harness ensures your timing signals are clean and reliable. The terminating design means no additional sub-harnesses required — simply connect the labelled wires to your Elite ECU and you're running.

ECU & System Compatibility

Specifically engineered for Elite 1000 and Elite 1500 ECUs when managing Mazda 13B rotary engines with Series 6, 7, or 8 CAS systems. The harness interfaces directly with the Elite's trigger inputs, maintaining the precise signal timing essential for rotary engine operation.
