I’ve looked at the info on the Lt1 site. It’s a great guide. I used the guide to put an ls1 in my son’s 90 Camaro, but I bought a 2015 engine for my 86. The information is there for 2010, 11, but not for 12up.
I have a crushed connector on the front of my engine, I think it is for the electric steering on the 2015 Camaro, but I would like to verify. Also need to know if the pin outs on the ecm are the same as the 2011.

 

Try ls1tech.com That's where the LS people hang out.

Here, we know, 82-92. A few of us dabble elsewhere occasionally, but that's the range we cover. We can help you out with the 86 part, but the others, are outside our scope.

Good luck with the 86. That car with that motor should end up fun to drive.

 

 

Can you post a picture of the connector? I can provide pinouts as well.

 

I attached the 2015 ECM pinouts

 

The connector is in the picture that i posted it’s at the bottom. Here’s a closer look


I’m pretty sure that it went to the steering, but I don’t know where the other end goes. PCM maybe?

 

It went to the power steering, but it is all communication circuits, so you will have to splice them for HSLAN to communicate properly

 

Ok, I guess I’ll have to study on this. I appreciate the help.
I saw a connector on the top of the engine too with 5 wires, all of them are blue ,some dark some light . I’m guessing these are communications too.

 

Light and dark blue almost always will be

 

I appreciate the pin outs that you provided, but they don’t match what I have. I’m wondering if my engine is a 2015 or maybe a 2012. The computer is an e 38 with 2 connectors. The info on the lt1swap site shows 3 connectors on the 2014-2016 pin outs . I thought maybe the trucks had different computers. My engine was advertised as a 2015, it doesn’t have a power steering pump. I’m not sure what year electric steering started. The harness info on the lt1swap site doesn’t match the 2011 because of the steering connector. Other than that I haven’t noticed any difference, but I haven’t even taken the harness off of the engine yet.

 

If you can, send pictures of the ECM connectors and the tag on the block that has serial number/identification data.

 

Here are the connectors




l will have to get the bock numbers later, I’m not near it now.

 

Here’s the block casting # .

I think the only thing that tells me is that it is a 6.2

 

Ignore the "k20x3" that doesn't apply. But X1 and X2 seem to match

 

Yes, I think you’re right

 

I got a chance to dig into the harness last night. I learned that the 5 blue wires near the ecm went straight to the broken steering connector at the bottom of the engine. Then there are 2 sets of tan- tan/black wires that go to the ecm(1set) & tcm (2nd set). I am guessing that I need to splice the tan & the tan/black from the ecm straight to the tcm. I haven’t been able to find any information on this anywhere, but I know I’m not the first one to run into this.
Can anyone verify this, or send me to some info on it?


This shows the blue wires coming from a connector near the ecm. Maybe went to the bcm

The 2sets of tan-tan/black going back towards the ecm.

This is near the ecm. You can see one set of wires going to the ecm , and the other set going to the tcm.

 

I found more information, but it’s 2011 info (I think)



This shows the tan-tan/black wires coming from the ecm to terminals 13&14 on the transmission. Another set of tan-tan/black on terminals 10&11 go to the headlight & the brake module.

 

Sorry, I didn't see your last post. That's correct, and they can be wired around.

"Why won't my car start?"
"Because your headlights have condensation in them"

True story

 

Great , so I should be able to splice 27 & 28 on the ecm to 13 & 14 on the tcm & just remove the other wires. Right?

 

I Believe there's another terminating resistor down line that you will have to add. I'll check in the morning at work.

 

Ok, thanks

 

Those are GM's "CAN-BUS" System Wires....
There is a High Speed Network for the EBTCM, SDM, VCIM, BCM, TACM, and PCM/ TCM.
The Low Speed Network is for the other 30 something Modules.
