I sure hope so because that is the unit I got for my swap but haven't installed it yet.

Either one of those will work-the first one you linked is what I have.

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 doesn't look right until you have it all apart and read the instructions,then it makes sense.

quick question for all the speedcal owners....

i got a mustang trans, and a 3.73 over the stock 3.27 rear end my car came with.....both factors to throw the speedo off!

what setting do i apply to it? no instructions really on the settings for that application

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.
