How to wire Speedo on TPI to Carb swap.
I have a 1987 Camaro 305 TPI vin F. I removed the ECM and the ECM wiring but I need to find out how to wire my Speedometer.
Thanks

When did they go to electronic speedometer?
So my speedo should already be hooked up then?
My speedometer on my dash will work?
Are you positive?

I looked into the Dakota Digital interface, called them and the guy said I should be able to connect the VSS directly to the Dash Cluster, and the cluster proccesses the signal to report the speed.

1987 doesn't need any of that.
It uses a cable. Same as cars had been using for decades prior.
The ECM gets its speed info from a little yellow box that mounts to the back of the dash and optically "looks" at the spinning thing the cable drives.
The Dakota thing is a great solution; just, to some sort of problem that actually exists. Which it doesn't here. There IS NO problem for the OP.
And of course, 87 isn't OBD2, since OBD2 appeared in 1996. (a few in 1995... but still far from 87) So, nothing that applies to OBD2, has any connection to 87.
