I have a 87 300E. The outside temp readout is bad. I purchased one off ebay and it has 5 pins. Unfortunately, mine only has 4 pins. I understand there is a way to adapt the 5 pin to work using only the four wires. Does anybody know the procedure?

Thanks.

Sam

The search feature is a wonderful thing. I searched on "300E temp display" and found this thread (among others). Might answer your question:
