Standard length harness for multiple coils applications. TR6 must be mounted in the stock location, coils mounted to the valve covers or similar. All LS2-style coils are compatible, but the coils with the metal fins are not recommended. Harnesses are made to order, so delivery can be 1-2 weeks, but the harness can be customized to your installation. This harness is not hotwired. When ordering let us know all the coil mounting details via email.
