You’re the man. Thanks for the help. Less and less reason to stay on DSource when you compare my identical posts. Over here I got some help with my question and a great deal on a gauge. Over there my post was ignored, probablyThanks mdubs! Glad We were able to help each other out.
That makes 6/8 wire (signal wire) red on the brake connector. I was mainly confused if the + (POS) was 6/8, or if signal.Those are the colors that match the STC4637 connector as I understand it (can probably check when I get home). The connector was intended for the brake lights.
See here for details all in one place: http://alre.club/Forum/index.php?topic=72.0 and you can verify the connector pins with the wires.
edit: Look inside the sender for the pin labels and you can verify. #2 at speedo to the + pin on the sender.
Vacuum gauge will not work on a diesel engine. Get the 30 PSI Vdo vision boost gauge with the npt fitting g kit .Which boost gauge do you have there? Do we need to see vacuum? And what do I need to get to connect the boost to the engine?
