need help from audio installation experts:
So as my car is close to getting here now I am preparing all the wiring harness so I can simply install the speakers and amp once the car gets here. I know about SVX 20-pin combined harness however $40 is a steep price for it when I know I can make the same exact item for half the price. From research I found Metra 70-7552 and 71-7552 can be combined to make the same item with SVX 20 pin harness. Can someone confirm this? I don't know if the wiring colors will be the same but I don't care as I'll be able to figure it out base on the table SVX provided on his site.
