I'm having a problem when i installed my PAC ROEMNIS2 i get no power to the radio. i connected yellow, red, and black wires but i get nothing. i connected my PAC to the new radio harness then plugged it into the factory harness. Should I run my own ground?

Car is a 2003 sedan with bose

 

Check your fuse, then verify power at the harness. If both of those are good, you may have a fault within the radio.

Have you tried to go back to stock to see if tha PAC is bad?

 

power is good, radio is good. what next?

 

Run your own ground, if the red and yellow wires are giving you +12v when the car's on, and the ground is solid, the radio should at least power up.

 

ok thanks i will try

 

+1 on checkin the ground
