Is there more than one Life ECU wiring schematic?

Hey all, i'm currently doing some modifications on my SR3. Among other things im adding solid state battery isolation, and removing superfluous wiring that went to things I no longer need power for. Im also moving things around for better weight distribution. I have pinged the wires and rebuilt pinouts from scratch for 4 of the 5 harnesses on the car. (paddle shift harness, chassis harness, Aim 'dash' harness, charge harness) and have built new master schematic that integrates everything together as i need it. What triggers the post is that I've been using the 'Life ECU and FI' schematic under the resource tab as a sanity check and have found its only about 85% correct to the OEM harness that I pulled and pinned. Most of the stuff is there- but its missing an entire 12pin deutch connector. The harness specifically that is most different that the one in the resource is labeled LH0192 gear shift serial No 42650. Does anyone have that schematic or know where it can be had?

I don't believe that pinout has changed in general in terms of coils, spark, injectors etc.

The plug you refer to will be for the paddle shift I believe which may not be detailed in early diagrams.

If you have rebuilt you paddle shift harness it should be connected to this and that will give you the pin out? Unless you are running on Geartronics paddles and not the later Life stuff.

Thank you Dan I was able to match up thing to about 80% using the logic method like you were describing. I was stuck trying to understand what exactly the ecu was looking for on 2 signal wire, I was able to infer it based on the stock wiring I pulled apart and the wiring resource. Unfortunately I had to cut off the loom boot on the ECU to have a look at which pin it went to then reshrink another one on when I was done.

 

Good news is its all running and shifting like factory now.
