Ok I mentioned before I am no good at wiring and it bit me this time, I pulled 4lb's of wires out of the dash, mainly a/c and radio out of my 2000. However the tach, water temp, and oil psi are no longer working. I have been searching for hours for a good schematic. I've been trouble shooting this all day and have come up with nothing, all the other guages work on it. If anybody has a source for a good diagram please let me know, Thanks!
