I am building a custom Express van, and I have a harness from one from a junkyard, but some a**hole cut the driver side fuel injector bank, and ignitor pack harness from the main harness.

So, i took the harness for the driver side FI bank and ignitor bank, from a pickup.

Here is what I have:

Express harness coming from engine side:



Group of 4 pink wires

Single pink wire

Single black wire

Coming from the fuse box side of the harness:

Group:

Orange wire

Purple wire

Brown wire

Blue wire

Green wire

Another group:

Orange/black stripe

Pink/black stripe

Brown wire

Brown/white stripe


Now, that is from the harness.

The connectors I got from the truck:

Injector connectors:

Ground of 4 pink wires (I assume are ground)

Black/white stripe

Black

Pink/black stripe

Red/black stripe

Ignitor connector from truck:

Black wire

Pink wire

Red wire

Purple wire

Brown wire

Blue wire

Green wire.


Based on what I can deduce, and correct me if anyone knows better please let me know:

FI Connectors:
Main harness groups from express van

FI connector sub harness from truck

Ignitor sub harness from truck


Group of 4 pink wires in harness coming from engine: connect to group of 4 pink wires going to the connectors.

Group of wires in harness coming from fusebox:

Brown/white stripe from harness to black/white stripe to connector

Brown from harness to black to connector

Pink/black stripe from harness to pink/black stripe to connector

Orange/black stripe from harness to red/black stripe to connector

From what I am assuming is for the ignitor:

Single black wire from engine side of the harness to black wire of ignitor connector

Single pink wire from engine side of the harness to pink wire of ignitor connector

Group of wires coming from fuse box:

Green wire to green wire

Blue wire to blue wire

Brown wire to brown wire

Purple wire to purple wire

Orange wire from harness to red wire to connector.


Hopefully the pictures help, with understanding the, "groups"

Thank you!

I am correct.

Orange is substitute for red, and the black is substitute for tan, pink is also positive. Hopefully we find out for sure, soon.
