ECU wiring

Am going to revert back to stock and remove the JB3. I had a question about stock wiring.

The big connector has black and white harness.
The small connector has the small black and grey harness.

Is this correct?

Also on the small connector how do you know where the connectors go? Do they only fit in one way or is the black connector closest to the windshield when put back in place?

How about going to burgertuning.com to see the video on how to install the JB3 PNP video? It should be there...

I did that. But there was no good shot that showed the original wiring.

Look how u connected the JB3 Connectors to the stock ones, and wherever you put the jb3 connectors put the stock ones connected to it in that same spot. I dont know if that makes sense lol. I just took of my jb3 pnp to take my car to the dealer, and it took me like 5 mins

A good way to do it is to do one connector at a time. Meaning slide out one connector, disconnect the JB3 connector, and slide the stock connector back in. Then repeat for the other 3 connectors. This makes sure you can't mix anything up.

Not sure if any of these are of the stock diagrams, but thought I would copy the link.
