Default Upgrading from Teves III to Teves IV Brake System

Has anyone done an upgrade to a TEVES IV (95-96)? As far as I can tell the module is on the pump with the TEVES IV and the on the TEVES III its in the trunk? How difficult is it to reroute the wires? Also the piping would have to be rerouted to the other side of the engine compartment, possibly more piping purchased.

If anyone has details on this please share. At least on the parts. Is this correct?

TEVEs III
Actuator
MC
Pump
Acc Ball
ABS Module (trunk)

TEVES IV
Booster
MC
Pump
Module (attached to pump)

Is there anything in the main ECU that will make things more difficult in the upgrade?

the ECU should be totally separate. The ABS is a standalone system. I believe other than linking up to the ignition and some other stuff for power, its pretty much by itself.

The easiest thing to do, by far, would be to find a junk/parts car and just rob the whole kit.

Are these both outboard brakes cars?

the systems are very similar electrically. I can't imagine different the wheel sensors being different, but if they are, it would be something else to consider as well

this is 1990-1991 and 1995-1996. I have an 88 so i know little about the differences in them. If the one you are talking about is 1992 or 1993 they are probably even more similar.
