Smiths Electric Speedometer

[RichieK]

The speedometer apparently is correct. It can get signal from the trans or gps. I was informed that my car was supposed to have the gps type speedometer and where to find the gps unit under the dash. When I looked there, while upside down in the drivers seat, I could not find it. I did, however, find a dangling plug containing red, black, green and purple wires. These wires run, in a black sheath, back over to the area on the speedometer but I can’t see where they go. I’m wondering if the gps unit didn’t get installed at the factory.

Richie,
If you have an electrical question about Superformance, wait for Blas to respond or contact him, he'll either have it on one of his diagrams or will add it after you figure it out.

If you are doing your own electrical troubleshooting, $60 for one of his drawings WILL save you a lot of time. Mine has a lot of penciled in notes and crossed out details that don't apply to my car.
