I am installing the motoscope mini speedo on my 1995 Sportster. I have almost all of it wired up except for Tach and Turn signal cancellation. The help I am needing is

1) I need to know the number of impulses transmitted from the speedometer sensor per wheel turn on my stock sensor. Also I am assuming since I am using my factory sensor I need to measure the circumference of the rear wheel and not the front?
2) My 1995 Sportster 883 didn't come with a tach. I am wanting to wire up this feature. I need to know how to find this.."Leads to the negative pole
(clamp 1 or -) at one ignition coil. In case of a CDI ignition you must use motogadget ignition signal pickup unit (article no 9000001" I am assuming that is one of the two post on my coil? If so how do I know which is which?

Any help would be appreciated. I included a link to the manual.

Thank You

Hi duaneduanet,

I am thinking about using the same speedo on my project.
did you ever get the speedo died in right?

If you have the stock speedo you can get the PPR in the diagnostics. Pink wire on coil for Tach, and turn signal cancellation is on the bank sensor and the TSM.
