This makes determining what pins your working with pretty much idiot proof.

You can also see that there are numbers on the connector.

I then add more solder to the individual pins by tinning each one (left connector). The connector below is how I receive them from China. Step 3:Preparation of the OBD2 connector. You don’t want to crimp the RJ-45 or solder your OBD2 connector only to find out you forgot to put these on the cable first. Step 2: Put on the RJ-45 boot and OBD2 connector cable protector. Solong as it sits stable between 506 and 560 ohms you are set.I use 510 ohm, 1/4 watt resistors, but other people have used 560 ohm, 1/4 watt resistors and been perfectly fine.

Step 1:First I test the resistor to make sure it doesn’t fluctuate all over the place. Here comes the guide on how to make ethernet to obd2 cable by yourself.
