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 LS^ 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.
