I am now the proud owner of a used 4.3TBI. I am in the process of trying to fit this to my 3.1.

The 4.3TBI is on the right. Here you can see the linkage looks like it is rotated 180*. It looks like it will take a little adaptation to get this to hook up properly. There are also three screws tapped into the side of the old TBI that are not present on the new one. It looks like I could drill and tap some holes however.

There are also differences in the what I think is the TPS sensor. I was wondering if I could try and find the proper plug and tap this into the wiring harness or should I try to fit the TPS from the 3.1 to the new TBI?

Many thanks,
