Instructions for yellow/green wire mod for using t harness in pre2010 chrysler/jeep products

0 votes
I have had no success and I see others have also met this problem and can't program their units. In the fortin app for Android it finally said canbus could be weak or backwards (the usual) OR that the modification wasn't made to the male side of the t harness where (don't quote me on this) you cut the yellow wire on the male side, add the (d1) yellow/green from your evo unit (from what I gather to the male side of the plug going back into the car side ) BUT . It says to refer to the installation manual for instructions (I've checked every version of the instructions and I cannot find this d1 wire used in any scenario). I really hope someone can illuminate this mod. Thank you
