2015 LS3 schematics needed
2015 LS3 schematics needed I'm nearly finished with the LS3, M10 Camaro harness. Just a few nagging issues that I can't find answers to.
1: ALDL schematic. It has changed from the Gen 3 stuff I'm used to. I did a Connect and cruise install and there were data lines in it I hadn't dealt with before.
2: X1 pin 18: serial data wake up. Does it get 12V+ from ignition
3: I can't find an output for a speedometer in my pinouts.
4: X1 27,28. I think these will go to the ALDL.
Anyone know of a source where I can print schematics from. The source I had closed.
thanks guys!

Depending on what year camaro (I'm guessing old)
X1 18 not used in your case
X1 27-28 (twisted pair) would go to TCM but in your case now go to the ALDL with a resister (I believe 120ohm) this is high speed LAN
gen 4 now get speedometer from wheel speed sensor or GPS

Thank you! I found the 27,28 info today also. ALDL 14, 6. I didn't know about the speed from wheel sensors. The PCM with a Connect and cruise has a VSS out for Speedo. I'm searching for that info from a prior build but that pcm had 3 connectors. Will I still need the purple wire in pin 2 of the ALDL, and if so where to?

they need to be twisted because it's a CAN bus, which uses a differential pair for "high speed" (usually 250 kbps) communication. Differential pair makes it much more resistant to electrical noise, twisted wire makes the differential pair most effective.

Verdad Gallardo The 2 data circuits are 2500 and 2501. From what I've found the 120 ohm resistor is in the PCM. I'll know today.
I find it interesting that the E67 PCM has circuit 818 for Speedo but the E38 doesn't. Just something I've discovered. Thanks for the help guys!

i believe you will need one at the ALDL also.
it doesn't seem you have any other modules so I'm not 100%
