| | | | Joined: Mar 2005 Posts: 1,636 'Bolter | | 'Bolter Joined: Mar 2005 Posts: 1,636 | Have any 4L60E wiring gurus here? I'm installing a complete LT1 engine and 4L60E transmission in an older vehicle, and have the wiring harness, except for where it connects to the stop light switch and the neutral safety switch.
I need to find a wiring diagram that shows how the stop light switch and neutral safety switch are wired into the ECM. What pins on the ECM are used for these two switches.
I have everything else ready to go. But the harness was cut where it went through the fire wall and I am down to these two switches.
This engine and transmission are from a 1994 Buick Roadmaster.
It is going in an old stovebolt truck.
If anyone can help, I would appreciate it.
