ls1 grounds

where are the grounding points for the ls1? I am about to fire up for the first time and need to know where the grounds are on the engine? I know the one from the alternator to the frame...... I have my fuse box grounded to the battery and the frame including the relays.
Also, the steam tube is connected to the nipple just below the filler cap nipple, is this ok? I am just trying to see my engine run before i send the pcm out to get tuned. I put the stock headers back on minus the egr? will it still fire?

thanks

Re: ls1 grounds

Grounds:
back of passenger head to frame
battery to engine block (big one here)
alternator to frame

The nipple just below the filler cap nipple is where my steam tube is run and it works fine. My egr is capped on the stock manifolds as well. Have fun!

Re: ls1 grounds

Heck, I've just added a whole bunch of grounds between different subassemblies. It's not going to hurt anything except for a tiny bit of weight - & it's such a trivial amount that it's not even worth worrying about!
