hi ya
pull ya knobs off (lol)
remove the 2 screws at the bottom and lift out where the vents connected to the heater system you will see 2 square holes block these with somethink to stop the hot/cold air coming out when using heater and having it hit the back of the gauges
fit the gauge holder with gauges and put back in the hole and screw it in carefully
i have seen 2 types of this holder one does not use the light panel attached to the back of the old vents and one does but cant quite see yours as picture is at a angle but if you have half moons just above where the knobs go then you will have to remove your light panel and fit to new holder
