Volvo parts ordering question

I think there's some volvo guys here. I'm trying to put one of the 04+ 40/50/70 series power steering pumps in the miata. I have the pump. I know the part number of the two connector housings it use (the plastic parts of the electrical connectors) but I cant for the life of me figure out what terminals and isolators go with the connectors. The connector part numbers are 30728420 (high power, large gauge wires), 30658215 (data wires). Calling the dealers gets me nowhere, they have no clue what I'm talking about. Some of the online parts places will give me a whole list of assemblies related that have a whole bunch of connector housing types and pins listed. I'm guessing those pins all fit, but I'm not sure. And I know they're going to have difference wire gauge options and terminal materials, but that information is only listed on some of the part numbers. If it comes down to it, in a few weeks I'll just order blindly and hope for the best.

I can't help from the work PC, but if you are okay with/know how to use torrents, do a search for VADIS and/or VIDA. They are the end-all-be-all parts manuals for all Volvo passenger vehicles. I think VADIS ends at '05 and VIDA picks up from there. I've got a .iso of VADIS on my laptop at home, if I can find a way to get it to you, it's a several gigabyte file. I could look it up when I get home tonight too.

VADIS doesn't like 64 bit operating systems much, I got mine to work on Win 7 x64, but required some special steps to install, and it won't work if you use any versions of IE newer than 8.

Have tried again and again to print as a .pdf but it ain't happening for some reason. Here's what VADIS has to say:

The power steering system is electro hydraulic and governed by the electrical power steering module (EPS). The control module regulates the power steering assistance based on input signals. This allows it to provide optimal steering assistance, irrespective of whether the vehicle is stationary with the engine running or is being driven at high speed. The functions managed by the electrical power steering module (EPS) are active when the engine is running.

The control module is under the right-hand headlamp. The control module and pump motor make up a single replaceable unit.

The electrical power steering module (EPS) is powered by the battery (30 supply) via a fuse in the integrated relay/fusebox in the engine compartment. The electrical power steering module (EPS) receives a 15 supply via the ignition switch and is unfused in the integrated relay/fusebox in the engine compartment and in the central electronic module (CEM). The electrical power steering module (EPS) is grounded in the left-hand suspension turret via a ground lead.

The electrical power steering module (EPS) communicates with other control modules using controller area network (CAN) communication.

If replacing the electrical power steering module (EPS), software optimized for the profile of the car must be downloaded into the control module. If this is not done, although the power steering will function, it will not be optimized to the profile of the car.

Signals

The table below summarizes the input signals to and output signals from the electrical power steering module (EPS). The signal types are divided into directly connected signals and Controller area network (CAN) communication. The illustration below displays the same information with the Volvo component designations.

Hopefully that'll get you an idea of what signals go where. I wasted too much time trying to make a .pdf, SWMBO is pacing the floor waiting on me to put the laptop down so we can leave. I'll try harder for the exact info your looking for later.

5.Terminal for power supply (30 supply) and ground.

The electrical power steering module (EPS) consists of one unit with the following main components:

-control module
-pump motor
-pump.

The electrical power steering module (EPS) is under the right-hand headlamp. The electrical power steering module (EPS) can only be replaced as one unit. The control module, pump motor and pump cannot be replaced as separate components.

Note! When replacing the electrical power steering module (EPS), the vehicle must be configured with new software to match the profile of the car.

Control module
The control module is built into the pump motor casing. All the electrical terminals are on the top of the control module. The control module has logics for all functions which enables it to read, write and store software and diagnostic trouble codes (DTCs). The control module also manages all communication with the other control modules via the controller area network (CAN). The control module contains a number of power stages, field effect transistors (FET). The field effect transistors control the output of the pump motor upon request from the control module. The control module also has a built-in NTC temperature sensor (low temperature results in high resistance, high temperature in low resistance). This allows the control module to diagnose, limit or disengage the power steering if an excessive temperature is registered or there are other faults in the control module.

Hydraulic pump (pump/pump motor)
The hydraulic pump consists of a pump and a pump motor. The pump is in an oil reservoir. The pump motor, which drives the pump, is under the reservoir. The pump motor is a brushless DC motor. The pump motor also has Hall sensors. The Hall sensor provide the control module with information about the speed of the pump motor, and therefore the prevailing hydraulic pressure (which is indirectly speed dependent). This allows the control module to control and diagnose the pump motor.

Signal specification

General All values given below are between the terminals stated in column 1 and breakout box terminal in the control module) and terminal B2 in column 1 (terminal in the Control module) unless otherwise indicated in column 6 (Miscellaneous).

Note! There is no wiring on the electrical power steering module (EPS) for connecting the breakout box. It is therefore important when any measurements are carried out that great care is taken to prevent short-circuits, damage to connectors, etc.
