Some of your text must have been cut off. Did you mean that the truck is all set now or have you still lost gauges Cruz and Jake's?

I already revised data harness connector truck give me hall information on my laptop but nothing came from gauges
Technician: Daniel Wilson,

Most of the time when you lose Jakes and cruise it is related to the clutch or brake switches. Check the Clutch and Brake switches 4 problems and proper operation as well as the wiring for damage.

Also check to be sure that your engine and vehicle speed sensors are working as a speed sensor problem can also affect your symptoms. Check the speed sensors and the wiring.

I'm mobile on my cell phone so I have no access to your schematics or anything so if this can't wait until I get back to my office I'm going to have to opt out so another professional can take over if you are in a hurry.

Sorry but this doesn’t help me I have this diagram. I told you in the beginning l checked every harness and connection already. Everything is OK.
Technician: Daniel Wilson,
 replied 3 months ago
If all electrical test good and you have confirmed power and ground to the gauges and the cluster is non-responsive then it is a problem inside the instrument cluster which needs to be either be replaced or sent out for repair. And for the cruise control since you have tested every switch and wire in the circuit and it all test so good that only leaves an ECM or cecu problem. Have you plugged into this with the paccar diagnostic software or caterpillar ET to monitor the parameters live in live data? That is your next step as well as possibly having the software reflashed and updated. Then as far as the cluster being dead after you have confirmed that you have power and ground there which you must because everything tested good. So it sounds like you've isolated it down to this. Let me know the results

And you dont have the old codes written down somewhere? Im going to opt out and let other professionals on the site chime in with their thoughts. Dont respond back or it will lock back to me.

I think I’m doing it tomorrow. I’ll connect everything back, start and move the truck. Maybe the codes will come back.
Technician: Daniel Wilson,
 replied 3 months ago

That is a datalink communication fault... the other modules are not recognizing the new ECM... If the harness is good and the power and grounds to the other modules it will likely be software related needing to have the Pete dealer reprogram the software so they recognize the new ECM.

You think l have to program Ecm or cab control module?
Technician: Daniel Wilson,

Was the ECM already mapped to the old one?

Technician: Daniel Wilson,

Cab control module. The ECM might still need a few tweaks or parameter changes if not mapped exactly to the old one.

Not sure if both bad or if there is a wiring issue or the other one is not recognizing the other modules... There are a few variables it could be
