The Plastic Lizard

I am hooking up a 1999 4l60e to a 2002 corvette ECM and then to a 1984 C4 Corvette digital dash.

And here is how I am planning to do it this weekend....feel free to comment.

First, this is the transmission, it is out of a 1999 Camaro. It needed an Advance Adapters #50-0405E to convert the tailshaft from the newer to the older. This tailshaft comes with a 40 tooth reluctor and sensor. That should equal 128000 pulses per mile.



I connected these 2 wires through my wiring harness as circuit #401 and #402 into locations 20 and 21 of my ECM. They are listed on my wiring diagram as VSS REF LO, VSS REF HI.

I then connected a wire from output 50 on the ECM as circuit 817 into the input on a dakota digital SGI-5C universal signal interface.



I connected 12volt and ground, left sensor ground blank.

I connected a wire from the OUTPUT #1 to the input of my 1984 digital dash.

I am not sure if I should connect to circuit 400 or 401 on the input to the digital dash. Does anyone know?
