Again. Using the pins I said allows you to use the same harness on all the vehicles I said. I know what I'm saying. Pin 59 is a high priority data line that is more I portent to the computer than pin 58. Just use 59 and call it a day

x2 on pin 59, They should update that help section

An aquaintance of mine that does bench top tuning and LSx swap harnesses uses pin 59
