On the recommendation of a few people here on the forums, I recently had my gauge cluster repaired by Tanin Auto Electronix. When I received it back, it looked like everything worked but then I turned my truck on and noticed a few funny things. I own a 1996 LX450 and I think what is going on here is that they replaced the guts with instruments from a Toyota or a different model year and the wiring is slightly different. Here's a quick video I took to show the problem. This is a triple-locked truck. I sent a support request to Tanin and they haven't responded. I was happy with their service until I saw this and they failed to respond to my repeated requests for help. $750 later, they failed to fix my instrument cluster and I can't say I can recommend them.
