INFINITI J30 WIRING STEREO INFORMATION 1995

and the wiring harness is where i am going to have to connect the wires from the deck to the car correct? please help my first time

the way i see it is take out the old one and plug the new in to the wiring harness which should be there? the stock one is a bose system PLEASE HELP


THANKS IN ADVANCE

 

buy an instalation wiring harness and color match the wires

 

Yea i want to ask the harness that i need to buy connects to both the cars harness and the decks harness, thats what i understand ?

i have everything the deck, brackets, but i need the wiring harness...

 

Yeah it saves you from tapping into the stock wires and cutting the stock harness. Honestly it will make it a lot easier for you to just buy a harness. it plugs into your old harness and you just connect the wires from that to the radio harness and they are color coordinated so you really can't mess up too bad
