okay i have a chipped p28 and a serial datalogging cable, the ends of the cable are labeled and i had always kept the cable plugged into the ecu but for some reason i unplugged it and can't find the diagram that Keven sent me with the ecu and cable that says what wire goes where.
can anybody help?

 

take a picture of the end of the pin. Does it have a brown wire on one of the ends? If so, that side is the CN1, and goes torward the ECU plugs.

 

the wires aren't all together. they are all seperate with their own piece that slides over the pins. need to know what order they go in. they are all labeled what they are like ground, Tx, Rx i just need to know the order they conect to the ecu.

 

TX to pin 4 of CN2
RX to pin 2 of CN2
Ground to pin 1 of CN2
+5V to pin 3 of CN2

 

thank you soo much

 

OK good stuff. I thought they would be already installed in a female 4-pin header connector.

 

that would have been a whole lot easier.
i better write the order on the inside ecu cover so i don't lose it
