8 Channel IGN-1A Inductive Coil to GM LS V8 Adaptor

Overview

Transform your GM LS V8 into a modern coil-on-plug powerhouse with this 8-channel IGN-1A adaptor harness. Purpose-built to interface Haltech's legendary IGN-1A inductive coil drivers with GM LS coil packs, delivering the precise ignition timing control that makes the difference between a good tune and a great one.

Technical Specifications

• Part Number: HT-130338
• Channels: 8 (complete LS V8 coverage)
• Coil Type: IGN-1A inductive coil driver interface
• Application: GM LS series V8 engines
• Connection: Direct plug-and-play to GM LS coil packs

Why You Need This

The LS engine's factory coil-on-plug system is brilliant, but getting it to talk properly to your Haltech ECU requires more than bodged wiring. This adaptor eliminates the guesswork and potential failures that come with DIY harness modifications. We've seen too many builds where poorly executed coil driver interfaces caused misfires under boost, inconsistent timing, or worse — coil pack failures that left customers stranded.

Whether you're dropping an LS into a Datsun, building a turbo LS Commodore, or converting an LS-powered kit car to standalone management, this harness ensures your ignition system performs exactly as Haltech intended. The IGN-1A drivers provide the precise dwell control and timing accuracy that makes LS engines so responsive to aggressive timing maps, particularly crucial in forced induction applications where knock control and timing precision separate reliable power from expensive failures.

ECU & System Compatibility

Designed specifically for Haltech ECUs equipped with IGN-1A inductive coil driver outputs. Compatible with Elite 550, Elite 750, Elite 1000, Elite 1500, Elite 2000, and Elite 2500 ECUs when configured with the appropriate IGN-1A expansion modules. Also supports Nexus R3 and R5 systems with IGN-1A capability. Contact our technical team to confirm the ideal IGN-1A configuration for your specific LS variant and ECU setup.
