I've had bad day's. I've been a little terse from time to time. Despite my efforts, I've posted technical errors on occasion. I'm far from perfect. But, in nearly 1600 posts, one thing I've NEVER done is call someone a jerk or any other colorful schoolyard adjective. Yet, in your self-declared benevolence, you've managed to accomplish it in on your fifth post. Impressive. And severely out of line.
I gave icapture advice that I felt was more valuable than telling him to connect the red wire to the green one. You're most welcome to dismiss that advice in a courteous manor. You are NOT welcome to make personal attacks. Don't do that again.
And how will he know when you give him the wrong schematic? Is it after his car doesn't start or is after it burns to the ground? Yes, there is more than one harness/ECU/schematic. If, on the other hand, icapture takes my advice seriously, his odds increase dramatically of recognizing a disparity. That is just one of the many reason's I suggested learning more before diving in. If that makes me a villain, so be it.
