[mr.happy]

What dose this black box do?The green & the green/red are cut.

Also what do these 2 plugs go to 1 goes to the blue plug that goes into the column.


Thanks Robert

I'd suggest poping that P/N into realOEM.com, It's a great way to figure out what those pesky unknown parts are.

I believe that's your OBC Control Unit but I could be wrong...

That is the fuel pump cutoff circuit which ties to the CODE function on the Full OBC

The black connectors in your hand appear to be for the door open/temp/memo chime.

Dammit, I knew it had something to do with the OBC...

the green wire comes from constant power from the battery when the ignition is turn on

the green red is power to the main relay/motronics etc.

The box acts as a relay, and if the obc has the code lock function enable it cuts off power to the main relay, which supplies to fuel pump relay power therefore cuts off the fuel.

If removing obc and these two wires are not solder together... well you have no power to fuel or main relay and your car wont start.

look for a green and green red wire taht has been solder or crimp together.

It look like they remove the obc and not the wiring harness, because those two plugs look like plugs taht goes into the internal temp sensor that feeds into the obc.

God I hated that thing when I had to replace it and miss an AutoX.

blue connector with the single black wire, is for the OBC scroll function built into the turn signle stalk. And as everyone else said green box is the OBC relay box, that operates the code function to shut off the fuel pumps.
Other two loose plugs look to be for the door/OBC chime module.
