ive got it. i love it. i didnt use any resistors or capacitors either.

 

How do you hook up the little plastic connector with the 4 wire holes in it? The instructions don't say how. There are 4 metal connectors included, but no extra wires. I'm guessing these are for the wires that plug into the HPTuners cable. Please help. Thanks.

 

The top left slot on the connector labeled for 3.3V goes to the gauge. The bottom left is a ground that you can hook the mode wire from the gauge to if you desire to have it read as lambda instead of the standard afr reading. The slots on the right side are both o2 outputs, the top one is a narrow band signal and the bottom one is a wideband signal which is the one that is used with HPT.

Without HPT you will probably only use the top left slot of the connector.
With HPT you will also use the bottom right slot.
