4L80e wiring. Pink wires?
I'm a little confused on the wiring diagram for the 4L80e.
There are 2 pink wires on the trans connector. According to this diagram, they go straight to the PCM:
So my question is, do both of the pink wires go straight to the PCM, do they have inline fuses, or do both ends run to a fused ignition source feeding power to the ECU and Trans?
According to LT1Swap, the pink wire in pin E on the trans plugged runs to the underhood fuse panel first. Does this mean that pin E is supplied power from the PCM on Pin 75 and has an inline fuse, or are both Pin E and pin 75 on the PCM both supplied a fused ignition source from somewhere else?
The odd thing is, it seems like 1 continous wire going from Pin E to pin 75 on the PCM. But according to this site, it should have ran to the underhood fuse panel first as circuit 1020. I'm so damn lost:
