Typically, we prefer you contact our pre-sales tech support department before purchasing a harness. This is a basic TBI harness for all engines using ECM 1227747 and 1228746 type ECM. Many others can be used. 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.
