An SR5 cluster will have a tach and oil pressure gauge and volt meter. Delux cluster will not have those.
To remove the cluster you need to remove:
-Lower cluster under the colum
-surrounding area (just pops off) - make sure you get the two bolts pointing up from in front of the cluster
-remove the heater control plate (paper clip works good to pry it out)
-remove 4bolts that hold the cluster in
-pull the cluster as far as you can, remove the 4 wiring clips (they only go in one way, so dont worry about mixing them up)
- pull the speedo cable out, or if its electric dont worry about that
remove the bulbs and replace. most LEDS are polarized so if they dont work, remove, turn em 180 degrees and try it again.
