This Plug-n-Play Harness is used to connect any of the Coils listed below directly to your RX-8 wiring harness without having to cut and splice into your factory harness.

This Harness adapter fits the Ignition Coil Packs listed below:

  • GM D581 (12558693) Truck Coil
  • GM D585 (10457730-Delco, 19005218-Delphi) Truck/Yukon Coil
  • GM D513A (12570616) LS2/LS7 First Design
  • GM D514A (12573190) LS2/LS7 Second Design
  • MSD LS2/LS7 Multiple Spark Coil PN# 82478

Our harness adapter is made out of cross banded high temp polyethylene TXL wire & OEM Connectors, pins and seals to ensure a secure, long lasting, moisture free connection at the Ignition Coils and at the Harness connector. These are the same components used by the OEM on the factory harness. Our adapter is built with 4" long leads to allow for mounting of your LS2 coils in the same location as your factory coils.

We build our RX8 to LS2 coil adapter harness using High Temperature braided fiberglass sleeving instead of  plastic convoluted tubing, this sleeving resists abrasion, chemicals, and under hood temperatures. This High-temperature sleeving allows close proximity to Exhaust & Engine heat without worrying about wire damage or plastic convoluted tubing cracking.
