What’s up guys. New here and did some searching but can’t find any answer. 01 gs300, put in 01 aristo cluster swap everything works as it should with the exception of the dimmer switch. It doesn’t work at all and it’s caused the hvac controls to have no back lighting when the headlights are turned on. The backlighting on the cluster works just without the ability to dim/brighten it. With headlights off the hvac has back lighting like it should. When turning headlights on the back lighting in hvac turns off. If i put the stock cluster back in everything works as it should. I’ve looked at a ton of pin outs for the cluster on the gs as well as the aristo. I have the pigtails for the aristo cluster and they are identical to the gs as far as location and color with the exception of the gs harness having one spare pin but i cannot find a pin out to tell me what that wire is. can’t seem to get a clear answer on how to solve this.
