Just want to let every one know 4runner lives to see another day. it was brutal. cut the floor board cuz doing this on the floor with barely an access . it was hard enough to do it from above...
basically followed a few videos out there. I saw someones youtube video where you can cut the floor board.
transmission harness going to the ecu had so many wires that just snapped when you touched it.
so i just cut the wires bought new transmission harness on amazon, and but splice + heat shrink wire and wired it up
I use 23 pin nails from my nailing gun and drowned it fluid film and hoped it worked. if someone in the future is reading this, you can full set the pin in and just shy of flush snip it. should be more than enough to make up contact.
it takes several tries to get it right. . but eventually you will get no codes.
its also a mother lover to get disconnected the first time.
