Lonnie sent me the one with the circular connector, not the D-shape like the connector on our cars.....this shouldnt matter should it? i mean, it just splices in between the EEC and the VSS regardless of connector shape, right?
btw, just saw your new times in your sig JL....nice!
It's very simple really....
Stock gear for the mustang is a 3.27 with a purple 21 tooth speedo gear.
So,use the speedcal program in dallas mustang's website and use the mustang stock tiresize of 245/45/17,21 tooth speedo gear,and a 3.27,then put in your gear,tiresize,and use the same 21 tooth purple speedo gear. That'll give you the configuration you need for the dip switches.

btw the standard 9910 wont work with a 04 4r75w in our cars. you need to use the extended range unit.
