Since we have so many international folks, I figure someone has to have done this. I am installing a Terratrip 202 and need to install the Speedo Pickup. I know it splices inline with the electric speedo, but not sure how. A friend said to take it to a speedo shop, I say it can't be that hard.

Any advice?

BTW this is on a 1990 Rangie with electric speedo, not the earlier mechanical jobby.
