I installed water and oil temperature gauges last weekend. I used the autometer phantom II because they were LED and looked like the stock gauges. I've installed many of the Issporo and wanted to try something new. The install was easy, however the Dodge light dimmer won't dim the lights on the gauges. I mounted them in the dual dash pod, so when the lights are on, they are like two headlights shinning at me! Autometer wants to sell me a dimmer module for around $30. 00, but i just unhooked the lights to solve the problem. Be warned of the bright lighting if you don't purchase a dimmer module.
