Hey i got 2 questions..

1st one- I have engine open I traced the fuel line to the fuel rail and i cannot located a plug or nipple to attach my pressure tested. (7.5 L 460 CI) I took the panel out from inside and I found where the line initially connects to the rail there is no connection i can use there. Anyone know where this is?

2nd question - where is the ecu located on the bus I've read about leaky capacitors and i wanna take a look... I see something that could be it under the driverside door near the fuel pump.
