Blown77Z Posted September 19, 2008 Share Posted September 19, 2008 I recently found a OBDII plug and have been doing a little reading on how to wire it up and want to make sure the wiring schematic is correct before I cut the harness. Here's a picture of the plug from ls1tech. I simply splice the purple wire from the OBDII plug into the dark green wire (PIN 58) on the blue PCM module? 58 DK GRN 1049 Serial Data Thanks Quote Link to comment Share on other sites More sharing options...
ColtGT4g63 Posted September 20, 2008 Share Posted September 20, 2008 Looks about right. I did the same thing with my Harness, and it works great! Actually just got back from a long night of tuning with HP tuners, fun stuff. Quote Link to comment Share on other sites More sharing options...
