Hey. so i am driving an audio 80(1992) and my dashboard dosent work. instead of buying a new one , since i aarledy have a pc in my car i was thinking of making an electroning. but the car does not have OBD... Instead it has Vag-com... does anybody know if i can use just a cable with vag-com / usb for digital gauges , or do i need anything else spacial? also the vag-com adapter on car seems prety simple. any1 got any idea if i can make up a vag-com adapter using the cables of a normal USB??
