You take a Headlamp and use the battery and Pull a Load over the wires thats in question
now have you checked for continuity yet???
sometime continuity ok but Fails Load test
Do continuity first its easiest for me anyway
Did I give you the pins to test the other day I cant remember????

--FICM PLUG END PIN#-------------TO------------PCM PLUG END PIN#--------

ALL these circuits should have continuity and carrey a Load Between them doing this will verify the condition of the Wires
The FICM plug you will be probing is the closest one to fron of truck FICM sitting install position
The PCM IDK what one maybe try to trace wires from Ficm to PCM by Driver Battery and locate it that way I have a Pic it wont let me Post it here
Normaly the Pins are Numbered on the Plug END you can see numbers when you unplug it
CLEAR AS MUD RIGHT???????

Scan for DTC maybe a helpful one my pop up too
Hope you find something
A load test would be using a Light and the battery strip a peice of wire and hook to battery positive and plug into harness and hook the light at other end basicaly want to make these circuits in question to carrey a Load across it the light should be bright and NO Flicker
But test continuity first as thats the easiest

Its best to use a BIG Light Bulb for Loasd Test pull as much juice as possible over it
them little test lights dont pull much
I think Cheezit has a HeadLight rigged up for this kinda testing

There you go thatsa IT
Maybe you can splice a new wire In would be cheaper than a Harness anyway try it see if it starts then if you want a new harness then so b e it
Thats the Camshaft Circuit from PCM to FICM
