Hellow everyone. Thank you in advance for checking this post and attempting to assist a fellow inthusiast. I have searched the different post on the site and still have a couple questions. I'm wanting to reset the SI lights. The car in question is a 87' 325i. The car does have a 20 pin connector and upon looking for the #7 Pin which has a green wire. The #19 Pin hole is empty. However, the #20 pin has the Brown (Ground) wire in place. So, I followed the procedure to jump #7 and instead of going to the empty #19 Pin hole I went to the #20 Pin (ground). I turned the ignition to ON and commenced to wait the 10 or so sec. for the inspection light to clear and the wire I used to jump the two Pins cought fire. Thankfully it didn't cause to much damage. (melted part of the plastic housing
). Any ideas as to what went wrong and how to proceed properly to reset the SI Lights would be greatly appreciated.
