Okay, I've worked out that this the module in my car its stuffed, this is the TFT module? ... that right? ... Its funny, i can put the motors together but never had a stuffed dizzy before ....

Is it easier to replace the whole dizzy, or just replace the module? How hard is it to do? ... also, any tips? ... please help, going to do it today ...

Also, are the 3.9 and 4.0 dizzy's interchangeable? ...
