    OBD-1 scan tool, any one know where to get a USB to OBD-1 (12 pin) cable, or tried (16 pin) OBD-2/USB to (12)pin OBD-1 conversion "jumper cable"

    The 5068 is the 94 HD IP used on 1 tons and will only work with the correct PCM. The 5521 is for all other rigs.

    Burning Main Fuses

    In 2000 on the gmt-400 trucks GM started using a 2 pin connector on the blower which eliminated the need for a housing ground.

    Your EZ-TCU does not use the brake switch/TCC signal. The OEM TCM does use that signal to control TCC operation.

    TPS question on TH400 to 6L80 transmission swap with a 6.2 diesel?

    The 32.00 military TPS will not work on your IP. The other 2 are the same except for the electrical connector & do fit your IP. BLK is sensor ground, BLU is signal, GRY is 5v.

    TPS question on TH400 to 6L80 transmission swap with a 6.2 diesel?

    Depends on which IP you have. These are 5v. TPS’s that fit our Stanadyne IP’s. 12554488 - fits military IP’s - throttle shaft end is different. 10137417 - 93-up 6.5 14071076 - older 6.2

    95 gasser temp sensor.

    Looks to be the auxiliary cooling fan temperature switch. https://www.gmt400.com/threads/are-the-coolant-temp-sensors-the-same.67524/

    It is the cooling fan temp switch. https://www.rockauto.com/en/catalog/gmc,1994,c3500+pickup,7.4l+v8,1147878,electrical-switch+&+relay,radiator+fan+switch,4312

    Misfire or broken parts 6.5 diesel

    That sensor is probably a temperature switch for a DB2 injection pump.
