2003 Mach 460 Replacement

[merc123]

I'm pulling my hair out. I have a Pioneer head unit and want to use all factory amps and speakers. I have an extra amp/sub connected to the amp rack with a Scosche RCA converter.

I bought three different Metra harnesses. The one that finally fits has three connectors and is the 70-5701 kit.

I matched color to color on the main, rectangle harness. The large square connector only had mute and power antenna so I color matched the mute to the Pioneer harness. The smaller square connector has amp ground, amp turn on, and RF speaker + and -. I connected amp connections but RF speaker connections don't go anywhere. There is already a RF speaker wire on the main harness.

I have sound and can move the fade from F to B and R to L and it moves properly. The bottom door speakers have no sound. If I splice both RF speakers wires to each other I get strong bass but lose fading and I get a muffled beep through the system when pushing buttons on the radio. If I disconnect the small square harness RF speaker wires and touch them with my fingers I get thumping through the sub and back speakers.

Is there a diagram that shows the pin outs for the car harness or anyone know the way to hook these up?

Seems like the two you have tagged as RF may not be correct. Can't be two of them unless it is the tweeters but I can't remember if they were both tied together. Are you looking for a diagram of the stock wiring?

I got it. I bought 3 different harnesses and got them mixed up. I was googling around and someone said use the 70-5519 kit by Metra. I noticed it had a white connector with RCA's. I was trying to fit a white one without RCAs. The other kit had a grey one with RCAs that was never going to fit. Finally found the white w/ RCAs and hooked all of those up and boom, fixed. The smaller, black connector runs your amps. I ran the turn ons to the switched power wire and negatives to ground.
