Blue is the number 6 wire coming from the canbus "high" connector. Pink or yellow is the "low" at number 14.

That is for the 05. Is the 04 the same? My bypass has only one wire to the databas.

found the wire I needed. Is there a way to test the data wire? (Like testing it with a logic probe?)

I don't know which bypass module that you are using, but there are two wires at the OBDII connector, there are two possibilities for your solution. One is a "high" output, the other is a "low". Depending on which mod you have will depend on which one that you'll use.

I'm now thinking I have a bad bypass. I have tried everything. Is there a way to test for these wires with a logic proe?
