Not sure if the reading discrepancy lies within the jump "around" the EGR computer, or in the junkyard replacement sensor I swapped in a month ago to try and fix the problem.
Either way, here's some pics for those of you that are diagram challenged. 
And my final product once I trimmed down the excess. I tucked it into the opening around the edge. |
Old thread, but there should have been a correction to this. I think Funolo mentioned it later in thread. Maybe it doesn't matter but the wiring pictures show 20-25 correctly as per the text, but the other jumper in pictures goes from 14 to 18 instead of 14 to 16 as per the text.
Seeing 20-25 worked in post 1, perhaps that jumper is all that was needed? I tried that but it did not work. So I added the 14-16 jumper and the tach came to life!
