reset your ecu by removing battery terminals 20 mins

in the future buy a cheap pack of multi colored zip ties at the dollar store and mark ea wire before ya cut em.....do this on the new connector with all black wires as well

where and what connector did you buy.....i need one

See page 3 in the PDF

+12V to terminal B1 (Pin 5) and B2 (Pin 2). Both are in the middle
All S Pins are grounded in a sequence when activated

Pin 1= S2 Light green/Black
Pin 2= B2 Black/Red (does not matter which Black/Red)
Pin 3= S4 Blue/White
Pin 4= S1 Violet/Red
Pin 5= B1 Black/Red (does not matter which Black/Red)
Pin 6= S3 Green Yellow
