Typically, we prefer you contact our pre-sales tech support department before purchasing a harness. This is a basic MPFI/TPI harness for all engines using ECM 1227730 and 1227727 type ECM. No others can be used at this time. Harnesses do not come with installation support. If you order a harness it is assumed that you either know what you're doing, or have installed one of our harnesses before.
