A few LS3 questions please

[GarethGTR]

Hi All

I am getting near to that magical start up moment :-)

But I have a few questions:

1. There is a sensor on the sump (big white connector) that is not connected to the LS loom. (well I have a loom for an LS7) Is this an oil level sensor ?

2. I guess that the red capped oil breathers all need to join up and go to an oil catch tank that should me mounted higher than the heads?

3. The LS7 loom that have has a small pig tail loom to fit the MAP sensor, but the connector does not fit, does anyone have the part number for a pig tail loom that will fit or for the correct connector?

4. There are are two hose connection points on the intake behind the throttle body. I guess the larger ID one gets blocked off and the small ID one goes to the fuel pressure regulator?

5. there is another hose connection point on the intake on the opposite side to the throttle body. I guess this also gets blocked off?

6. The fuel return to the fuel tanks goes the lower connection point right? if so the the connection points at the top go to a breather? one way valve? or what ?

Thank you kindly in advance.

Regards,
Gareth
