first of all i would never ever use a test light on a newer vehicle EVER!!!! Especially with newer ECM's BCM's ignition harnesses etc. If that thing draws more power than any of those components can handle hope ya got an extra 400+ dollars laying around to replace a computer. ALWAYS ALWAYS ALWAYS use a digital multimeter (DMM) when measuring electronics in a car!!!!
