7.3L Wiring Schematic Printable, very handy.

7.3L Wiring Schematic Printable, very handy.
Handy Wiring Diagram that shows a Paper Trail of how the Electrical System Works for the 7.3L Powerstroke Engines, all Trucks, Excursions, Vans.

It was a Copy I had to PhotoShop to make it Readable & Printable.

it's very detailed and shows how every wire for each component routes to the PCM.



Use the Page Setup Mac or Properties Win and Print the Image Orientation, click Landscape,
it will fit most of the page this way.

best,
Russ

Good stuff, guys.

Moving into the 7.3L Engine & Drivetrain FAQ subforum so it doesn't fall off the radar.

can someone post the stereo schematic, my posts seem to have disappeared, and I need it, bad. got my stereo wired, all works but the back speakers seem low on power. They sound muffled, and I have to put almost all power to the back to make it sound even, if I move it slightly to the fronts, they take over and drown the backs. Could this be reversed + and - on the backs. Fronts sound good, wires to back must be right as they are working on proper sides, but just sound weak. More bass like, fronts nice sound, more treble. Any ideas

as long as we are talking electrical i do not know if this is the right place to ask this, but in my 2002 f 350 7.3, i am having radio/power window problems. at any time, running down the road, engine running and parked, cold start, or any time my windows and radio go off. the clock display stays on, and i do not loose the memory. power may return at any time, 1 min to 1 day. i have changed the fuse panel, which worked for about 2 weeks, then problem returned. i have since tried ign sw, and moving/ replacing the acc delay relay, but problem persists. any thoughts on this??? even on a site like just answer, anyone that tries to fix it thinks about it then runs away. there are other posts on this site about the same problem. sorry for the long reply.

Any luck finding the problem? My windows, radio, dome light, gauges stopped working. All fuses are good.

Hope this helps. (attached should be a PDF if I did it right)

New Diagram for the '02 Boys

I have been playing around with some software and built up a single page wiring diagram for the '02 trucks. They are basically four separate pages I had which I morphed into one large page through Photoshop. I then used another program to color in the lines to make it a bit easier to follow. I also color coded sensors, switches, relays and modules alike to help in finding the different ones.

It should provide good information when troubleshooting and for the most part can be used for 99-03 trucks. The wires will be different colors and pin callouts will be wrong, but the major portion is similar. It will if anything give you the right idea to figure out "how it works"

I printed a copy out 24"x60" and it is nice, 36"x60" would also work well. Makes a great poster on the shop wall. Just take it to your local print shop and they will have no trouble doing it for you. It is large enough already, you will not loose any resolution.

The pdf is located on my website here: Woodnthings Wiring Diagram

And a picture of it to check out!




Enjoy!

Did you by chance ever figure out what the cause of your problem was? I am experiencing the same problem with my 2003 F350. Thanks.

Mine has same problem, If i open the door and smack the side of the dash (the part that would be hidden by closed door) It seems to work again. Thus I am guessing the problem lies with a loose connection behind there. I think it may be the timer that controls the window and radio after you shut the key off but you still have the door closed. Its annoying but not annoying enough yet to rip the dash apart for me. Erich

I have been having a bunch of random electrical problems. Turns out that I have a windshield leak that is running onto the ECM. Apparently, it is not as uncommon as you my think
