wrong. you need two more #74's for the climate controls.Again, the ones that they sell in Dealership are not going to make your Cluster light up Amber, so get the Dealership out your head. They will sell you the same exact Bulbs that you currently have on the Cluster, so you dont want that.
You can get Amber Bulbs from Advanced Auto Parts or Auto Zone for like ~$8.00 total. Take 2 of the Bulbs with Sockets from the Cluster with you (The Big one and one of the Small ones) and buy accordingly. You will need 4 of the Small ones and, obviously, one of the Big one.
Oh and yes, you only have to change those 5 Bulbs to get the Amber Lighting.
OP- one of the best write-ups ive seen. very detailed and not afraid to include a lot of pics. good job
