2004 chevy silverado gauges not working

Unread post by Silverado2004 » Thu Aug 07, 2014 7:22 pm

I have a 2000 chevy silverado and i did an engine swap from a 4.3L motor to a 5.3L. But the engine i installed its from a chevy 2004 and bu the time i was finished with my truck, i noticed that the gauges weren't working. I turned my truck on and none of the gauges weren't working not even the RPM. So i connected my computer scanner to see wat it was and as soon i plug my scanner on the PED connection, the gauges started working and i disconnect the scanner and it stopped working. I already cheked all the ground wires and i doubled check if i had missed a harness connection but everything was connected fine.. I already have like 3 weeks and i cant find a solution to fix the gauges.
