Got a few questions.

Well I ordered my stuff to make my harness standalone per lt1swap, well it was saying I needed 2 30amp relays so I ordered them but allelectronics.com sent me 2 40amp relays. Will these work? I would assume they would as long as they aren't less than what is called for, right? Also could I get some pics of the o2 sensor plugs that aren't needed and also what is the plug in the back top of the block beside the cam position sensor? Oil pressure sensor? A pic would be great because somehow my block fell off the stand upside down and trashed both sensors and and I dont know what they look like to verify where they are on the harness. Thanks!

Oh heres some pics of my block tore down just waiting for a day to go the the machine shop to get cleaned up and checked out.

Drivers side

Passengers side

Here's two of the pistons, one side of the block all the pistons were like the one on the left and the other side of the block the right. Kinda weird I guess maybe a bad head gasket or something? Bunch of the guys over at ls1tech said I should just trash this block and get a new one but I dont think its that bad, can always be bored!

As long as the block is not cracked, it will be fine. IMO, I much rather have the iron block than an aluminum one, they are virtually bullet proof.
Also the 40 amp relays will be just fine.
The one plug that is threaded is for the oil pressure sensor (light or gauge depending on the vehicle).
If you need pictures of the sensors, it can be found here:

Thanks. Is there a plug on the wiring harness for that? Its like an 01 5.3, I dont remember seeing anything plugged into it when I got it but I dont know.

What is this plug on the right? The gray one, also what is the one with the orange? And I assume the center is the maf. Thanks

The connector on the left, with the pink, black, purple and tan is the O2 sensor.
The center with the purple connector is the MAF.
The gray connector connects to the sub-harness for the coil packs.

Connector Identification based on actual picture of part courtesy of AZ. Search and ye shall find.

That big gray connector. Not for coils, they're both tan and I do have them labeled lol i traced the wires back and they all go to the factory fuse box so its not needed right? Since I've been yankin stuff out of there anyhow.

My bad, I didnt look at that connector close enough to see the number of pins.
I would suggest getting a subscription with alldata and then you can get all connector information you need to be able to modify the harness.

Its cool, you have been lots of help and I'm about done with the harness now. That gray plug was my last thing holding me up had I traced it back to begin with I would have known. I think its a body plug of some sort, I'm not real sure I just know I don't need it. All I have left is building the fuse block. I guess it should be fine under the hood? Not sure if it would need to be located inside.
