can i ask what the purpose was to all the rewiring? i'm not following, sorry. looks good! now all i need is for someone to reprogram the processor on these things to say SHO instead of OFF and have the outside temp work like it does in newer cars, as in it stays on untill turned off or another button is pushed.
Here is how to keep the outside display so it does not change back. Wire in two wires at the points shown on the back of the CB. Connect these wires to some sort of maintained switch to keep the wires shorted. As long as it is like this it will stay. Turn the switch off and then there is normal mis behavior.
