2004 GMC 2500HD lost electrical.
i have recently swapped out my factory radio for an aftermarket dual din with
bluetooth . after doing so i have lost a number of things on the truck . i have
lost my Temp , Fuel , Battery , and oil pressure gauges . also lost my door
chime buzzer . lost my reverse lights and my interior dome light . i have
checked all fuses and found a fuse that was blown for the interior light and
got it working again . im at a loss regarding the remaining problems . i am
aware that the chime buzzer is operated through the drivers door speaker .
the speaker does work with the new radio . is there a relay for the gauges .
my speedo and tach still work with no issues . any help would be great
truck is a 2004 gmc seirra 2500 HD reg cab long box 4x4 6.6L duramax with

Hi Tom . Thanks for the reply . I wired the radio accordingly to the wire diagram for the vehicle . The neg battery cable was disconnected at time of install
