While in STAR wiring click on r12/42 in wiring diagram should bring up option to display associated connector/pins. I do not have access to STAR at the moment otherwise I would do it. And yes it would be best to identify equipment to pull relevant model year diagram. Also check wiring diagram legend for U848, U859, U958 & U831 explanations.
ODBC has zero knowledge of wiring, that would be like asking a network of computers where their ethernet cables are physically routed... they don't know or care, they just know they can send data back and forth.
There is a special feature in Xentry, where it can show connector pins OUT and shape, it is under guided troubleshooting....but the car need to be connected to the xentry.
I have not seen such facility in WIS for connector pin out and shape , maybe I need to search more
meh, I land on the same diagram S-prihadi attached a few posts ago, the wire colors line up with the pelvis airbag squib (R12/41), which is in the outside bolster of the seatback, and the headrest 'neckpro' solenoid (Y24/12), but there's no 4 pin connectors shown, they both plug into the same X55/3 which has a lot of pins, and all wires are the same colors on both sides. white/grey and white/red are the squib, brown is the ground, and yellow/red + pink/green are the neckpro solenoid if that feature is present (its not on this car)
what tossed me before, is the wiring diagrams refer to driver and passenger seats, when they really mean left and right, so a RHD passenger seat is actually labeled the drivers seat in the diagrams. the other seat has entirely different colors on the squib (brown, black, black/yellow).
This may be simplistic, but why couldn't Joe just pull the seat bottom, then he would be able to see the wire block and position the broken connector in its original configuration, then write down which colors went to which? usually a connector doesn't break off evenly so he should be able to position the connector accordingly, I believe he will need to remove the other half of the connector from the wire block anyways? I may be missing something here?

yes that sounds right because that seat needs a bypass surgery - - another field option is to compare with opposite side seat for a chance of matching colors.
(pelvis/knee airbags are related to the driverside dashboard assembly).
per the diagrams S-Prihad posted, the left and right pelvis airbag squibs have different colors
... there's a pelvis airbag on passenger side - I wonder where it is located... on the side of seat backrest ?
That means both seats wiring colors may not match.

Aha so that is how the YELLOW INTERCONNECT BLOCK male pins looks like disconnected with pins visible. Thanks Cali.
So this is a Male-to-Male Pins InterConnect Block and all incoming or outgoing connectors are female terminals. This InterConnect Block is not shown on the WIS.
John,
You need to verify, the broken connector of yours, is that connector location at the front or rear of the seat ?
It seems thru all videos I seen, the front is VEHICLE wire-harness incoming side like how Cali showed and it is a mono block.
If the rear ones, that is to the devices side and it seems from your photo, there are a few connectors and not mono block.
So if there is a wiring harness involved ( seems so from your photo ), it probably is the SEAT INTERNAL wiring harness and not the VEHICLE bigger more complex wiring harness which leads to X55/4 or X55/3 connector block.

Red circle no 1 is probably where your connector is broken at ... yes ?
If so, that seems to be SEAT INTERNAL wiring harness and the label of the harness P/N should be on it, white plastic/paper label.
The ODBC code can help single out the affected SRS circuit:
- belt buckle switch (2wires)
- child occupancy array (...4w?)
- pElvis side airbag circuit (...4w?)
- headrest pro solenoid (2w)

Wow there is alot of replies, Sorry i havnt got back to anyone iv been away.
So ill try to answer as many things above as i can.
I say a reply asking why i couldnt just match the square of wires up to the harness again and write down the colours --- i did think about doing that but the wires im holding are sort of twisted as the 4 so i wasnt sure which orientation the 4 wires go back into the harness. so didnt want to risk anything there.
S-Prihadi - If im understanding your question right then the wires im holding are from the back of the harness - back of the seat so im sat in the rear passenager seat to get to those.
Well im at a complete lose here, spent a few days going over the internet trying to find out which they connect to and cant find anything. Im going to un-bolt both from seats on saturday and try to compare and make good on the passenagers seat. Wish my luck.
Going to disconnect both batteries before hand and hope for the best.
I unbolted both seats so i could compare and the drivers seat does have the same colour wires as the passenager,
White and grey
Brown
yellow and red
Yellow.
Although these connect to the exact same colours on the opposite side. So my passenager seat connects to differnt colours to the drivers for some unknown reason.
Im done for. thinking of setting the car a light and claiming on the insurance
