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 hotwired (there is an additional relay so that the coils are powered directly from the alternator). When ordering let us know all the coil mounting details via email.
