I am looking to connect the signal output of my TKO 600 to the GM truck computer in my 69 Chevelle. I know that the connection on the computer is made to pins 20 & 21. My qusestion is about polarity of the connection. The output wires on the trans are yellow and violet. Is there a correct polarity for this connection or does it not matter?
