	Powering the ECU for my B6 2.7T Swap... Need B5 S4 help « on: January 24, 2012, 09:33:23 AM »

Hey guys, so I have the car almost done and it's just about started

http://www.youtube.com/watch?v=4XdwODnsrfQ

But it's not getting fuel, meaning the ECU isn't triggering the fuel pump relay, meaning the ECU might not be on, meaning that I might have my wiring wrong...

Using this diagram

I have pin 62 getting the 30 terminal, but it says pin 3 gets the 15 terminal (switched power), which looks like the black wire with the blue stripe. On the B6 the same wire seems to not go to switched power?

If I recall correctly, pin 3 is switched power based on the ignition.

You should attempt to communicate with the ECU via NefMoto or VAG-COM to make sure it is powering up.

Yea, wish I could make a bench harness. Unfortunately I don't. When I get down to the shop I might have one. We will see.

Can't you just use the OBD port on the car?

Why are you even looking at connections on the ECU?

The stock harness just plugs into the ECU and shouldnt need touched.

The connections all should be made at the 5 multipin plugs that join the engine harness to the car.
