I got a 92' SC300 with a 1jz swap. My problem is my temp gauge doesn't work. I search the forums and everyone says to solider a resistor to the back of the cluster, but what size resistor will I need?. Also my car's speedo and reverse lights don't work and when I checked it out, the trans in my car has a cable driven speedo and the harness for my reverse lights is disconnected. I want to know what trans do I have in my car and how can I fix these probems? Give post me links to forums that would help me...
