These are brand new harness sets for remote mounting of ignition coil packs. This will give your relocation a clean look in comparison to re-using a factory harness. These are for LS1 and LS6 style coil packs only. They will NOT WORK on truck, LS2, LS3 or similar coil packs. Two harnesses are included, each harness attaches to 4 coil packs.
These are meant for use with relocation brackets and will not work with factory brackets.
