Default Can somebody show me pics of all grounds on a Lt1?

I need locations of every ground wire on a 94/95 Lt1. I need to make sure I haven't accidently severed a ground with my swap. As some of you all may know I am having some crazy problems with my car at the moment. Refer to my $$100 Dollars if you can fix it post. TIA

One of the Cables off of the Neg Terminal of the Battery goes to the Passengers side Motor Mount on one of the Bolts. On the Drivers side there is a Grounding Strap that goes from the Drivers side Frame Rail to the Block somewhere, I had it bolted to where the AIR Pump was. On the Drivers side Head there are Grounds bolted to that from the Engine Harness.

There are a couple of grounds bolted to the Front Core Support, one on each side.

If you have any doubts, install some aftermarket grounds yourself. That's what I did. You can see one of them on the driver side, just below the cylinder head:

So how about this? I disconnected the grounds going to my coil/Icm studs and fired my car up and it runs just the same. I also disconnected the PCM ground and it runs the same. What gives here? I thought maybe one of my grounds was bad. Turns out the car likes running without them too. lol

Where was the ground located for your pcm and what makes you think it was your pcm ground? Also if your talking about the ground cables that go to the icm thats for the engine harness and really shouldnt run at all.
