I installed right now the aftermarket HU in Infiniti I30 96 with bose systems, with new speakers, i know have to do the bypass, I remove the Old HU, but i find in the bottom some black box with two connectors in the front and 3 or 4 conectors in the back, i not wanna do the re-wiring in the whole car i just wanna use the old wiring, which conector i have to unplug and tap from there to the new HU.

Thk

 

what year max? im not sure about the black box that you speak of. i just put in my new hu, and yes i used the stock wires.
