I upgraded form a OBS F250 SCLB 7.3 to a 2000 F350 CCLB. Really clean truck. Got it for 9k, so based on where I’m from that’s a steal for a 7.3
But it came with some issues that need to be ironed out. Figured I’d hop on here and bounce a few things off you guys and see what I get.
1st is I went to hop on the highway and gave er 3/4 of the onion and a Check Engine light popped up and stayed on after restarting the truck. No loss of power or nothing. It has an Edge tuner on it and was wondering if the ****ty tunes from the edge caused it or if it was caused by the HPOP undersupplying the injectors?? Any other ideas or tips would be appreciated.
2nd is he said the light switch **** the bed on him so he jerry rigged 2 generic switches into the circuit to get power to the headlights and running lights and the other he said was for power to the radio? I also have no interior lights (aside from the map lights) or dash lights. Not sure if that’s how the circuit runs but if I get a new OEM switch it should fix everything right??
It is a vast resource of knowledge, experience and kindness for our era of trucks and vans.
Second, I would invite you to create a signature for those that are interested in helping you. This way they might easily identify what year and model truck you have. Mobile users will need to view the desktop view or go to your profile, but others will identify your vehicle specifications quickly.
As for your CEL popping up when you were entering the highway, it could have been a couple of things. Since the CEL went away, it was likely an "over boost or ICP too high or low" code (DTC). Either way, the code should be stored in the PCM and viewable through a program like FORScan or FORScan Lite (FSL).
The links above were taken from the 7.3L PSD Tech Folder and I would invite you to start with the last link created by FTE'r BWST in an effort to help anyone out that was interested in reading DTC's and resolving issues with their 7.3L. If I were you, I would start there.
We tend to recommend old tuners/chips like yours be removed and something more modern like a Hydra chip be installed. There are many, many tuners out there available to you and will send tunes via email. The TS chip is still somewhat popular and supported, but the device needs to be sent in for tuning updates or changes. Although, once you find a tune you are happy with, the chances of looking for another are reduced.
As for your lighting issue caused by the PO, I would recommend you pop out the connector (wherever that may be now) for the headlights and see if the harness was tampered with at all. Splices, cuts, branch circuits, etc... If it has, we can supply you with a wiring diagram and connector pinout to repair the harness. The fix may be as simple as a new OEM style switch. It takes just a few seconds to pop the switch out, but I don't know what sort of rigged system the PO had, so it may take up to 240 seconds for you...
Keep us updated, we can help you out in whatever way you need. Again, it is nice to have you with us.
Dash and radio illumination goes through the switch, replacing it should fix everything if nothing else is mucked up.
The dome and utility light should still work when the door is opened though.... you might check fuse #10 under the dash.
3/4 onion?
I like the updated tailgate and mirrors, now it's time to update the headlights.

3/4 Throttle lol I watch this guy on the LubeTube called Zip Ties and Bias Plies and he uses onion scale instead of throttle position lol.

CEL did not go away. It’s still up. I appreciate the hospitality and the invite, thank you!! I am aware of the Hydra and TS, I have a Hydra on my OBS and I love it. I figured it might be something with the tuner I’ll mess with it today and see what I can get out of it. Thank you for the advice!!

My mistake on the CEL going away... I misread the post earlier.
Yep get the Forscan, read it, spend some money and time wrenching and have a great truck people are jealous of. I picked mine up 2 years ago and had to throw some parts at it and the fine gents here sent me on the right path.
these old trucks are amazing once ya get them sorted. Report back with codes and the smarter people will help you out.
Great site/Community here!
Today was my first day off so I was able to sorta kinda tear into it and see what the PO did. All wires were cut and blade connectors were put on them. So I have to find a wiring diagram and whatever connectors I need, also I cannot find the correct dash fuse diagram. Any help with those 2 things will be extremely appreciated.
Khris Jackson that is one heck of a truck for 9k, you definitely stole that one especially with today's market! As others have said forscan is your best friend when diagnosing these trucks. Not sure if anyone has mentioned it already but the failure prevention thread in the tech folder is a excellent read and will get you on the path to a nice reliable truck. Get ready to open your wallet as the guys on here are very good at spending other people's money ( in a good way). Seriously though the guys on here are great and have helped me out many times, welcome to the club!
