Re: Using an electronic speedo with TBI and 700R4?

So if I get one of these units, do I need to connect A10 to this and bring a signal wire from there
to the speedo?

Two wires from the VSS go to the DRAC
A separate signal wire goes to the ECM
A separate wire goes to the instrument panel for the speedometer and odometer.
Your 1986 does not have RWAL (antilock) so you don’t need that wire.
I suggest getting a wiring diagram for a 1991 to get all the connection to the DRAC.
There is a wire diagram in the post below. This is the best I can find at the moment. I lost my computer and all my files and links that I had saved.

If it is modified from what came stock from the factory, let us know that too.
