LEDs need to be installed from the front. To do this all that is needed is to take out the gauges by removing the screws on the back of the cluster and install the leds in the socket from the front.

This is not the easiest part to install. Not for a beginner. It was worth the effort though. The change in the appearance of my gauges was dramatic to say the least. Now I need the fire lighting to complete the look.
