i installed another instrument cluster from an 03 SSS and had SERVICE BRAKE BOOSTER come up and the battery light was on, my SES light stays on so i dunno if that had came on!!!!! I put the stock cluster in and both the above codes or lights went off so i took both of them apart and installed the Trans temp gauge and white overlay onto my gauges and put them back in so i think we might try again tomorrow and see what happens

Thats called reading the vcm. If you try to acces the vcm you will get the number 3 and it will say NO basically.
If you open the scan section of hptuners....you can start a log once you have the truck running. Start the log then pic how you want to veiw it...like gauges or table graph so on etc.
You can scan and log a locked pcm i have done it several times.
