So I've already removed all unnecessary wire for my build and I'm stumped. I'm a newb to wiring and need a dummies guide. But my situation is that I'm wanting to use the stock fuse block for my harness and have just connected the C2 connector to the fuse block and need help with the other wiring coming off the PCM and where they go. Here are some pics of what I have.
Here's some more detailed info of wiring coming of PCM:
Red connector- MIL control pin46, fuel pump relay control(green white stripe) pin 9, engine speed output signal(white) pin 10, vehicle speed output circuit 4k(green white stripe) pin 50
And I believe I also need the C1 connector because it has C1-B11 Red wire- Feeds 12vBatt. to ING switch and C1-A9 Pink From IGN switch hot in RUN, START. Powers fuse block up. And I think I need the C3 connector which has a wire that power fuel pump? Again I just want to use the stock fuse block. Also I need to know where the positive and negative battery cables pictures connect and where they go to. Thanks.
Okay right now I already have all the power supply associated with C2 connector figured out. What I'm asking is where does the Battery PCM Supply (orange wires) and ignition supply PCM (pink wires) go? Do I just run a wire from battery to orange wires? also Where does my fuel pump relay control wire go on the stock fuse block?
You can run the orange wires to the battery or even the battery terminal on the fuse panel, but you'll have to put an inline fuse in there.
The pink wires can go to any ignition source that you can find, but again, will need a fuse.
Your fuel pump wire needs to go to the fuel pump relay. If you're not using the stock fuse block to power your fuel pump, then obviously you'll need an external relay.
Im doing some searching and I think I'm finding my answers. Im trying to figure out where my orange and pink wires hanging off PCM would connect. For example the battery PCM supply(orange) pin 57 on Blue connector would connect to the C2 block at location B8?
So the wires hanging off my PCM. If Im reading the schematic right Pins 57 and 20 on blue connector would go to location B8 on C2 block. Pin 19 would go to location C11 on C2 block and pin 75 off blue connector will go to location F2 on C2 block?
