Are you refering to the harness that plugs up with the factory harness going to the factory amps? Or are you referring to the HU wiring hsrness that goes to the new HU? If you are talking about the factory harness, is that why you are waiting on a replacement harness? The harness I seen (pictures online) have the amp power on wiring with the RCA plugs. Not sure if it is your new HU harness. What kind of HU are you going with?

 

Ok,

So the amp on wires "blue/white, with rca's from Crutchfield as see below, you saying to tap both of them into the input and output leads of the radio shack voltage regulator?

To be more precise with flow of power lets put it this way:


Head Unit (Blue Amp On Wire)----->input of 5v regulator----->center of regulator to chasis ground---->Regulator Output---->Ford Wiring Harness Blue Amp on Wire (this is to the harness pictured on Crutchfield with the RCA plugs)---->this wire leads to your factory amps. Does that make sense?

The voltage coming from your Head Units Amp on wire is 12v. By passing it through the voltage regulator, you are reducing the voltage to 5v. Hence the output is now 5v instead of 12v. Now you connect that lead to the factory amp. Which is done throough the wiring harness with the RCA plugs. By doing this, you will avoid the loud popping discussed in other threads. I will be wiring mine up this week. When I do, I will post pictures. But it won't be until Friday at the earlies.

I forgot to add this. Since you only have 1 Amp on from your head unit, you will take the single output from regulator and connect it to both of the blue Amp on wires on your harness because you are feeding two amps.

 

Very good write up, only thing left is

Head Unit (Blue Amp On Wire)----->My wire harness, not the two blue ones on the rca since were going to soldier those together to the output of the regulator. The only blue wire from the main wireharness has power antenna written on it.

 

See Pic of only solid blue one.

How will you go about connecting these wires to the regulator,since the pins are so close?

 

I believe power antenna and amp on are really the same thing. They serve the same purpose. So That is the wire from your stereos harness that will go to the input of the 5v regulator. You can test this with a meter prior to installing into the regulator. When stereo is turned on, that blue lead should test at 12v. And when you power stereo off, it will go to 0v. But I think you are ready to start wiring.

 

Thanks!

 

I got one of those solder boards from radio shack. It has a bunch of pre-drilled holes, all close together with a ring of solder/metal contacts. It allows you to connect the dots by soldering a circuit however you want. I will be doing that.

I will wire my wires to the 3 "<" marks. So it will space the wires out. It will make it a bit easier to work with. I also purchased a project enclosure. Its about 2" x 2" big. This will seal the entire regulator and wafer board and hide the soldering job. It will have 1 wire into and then 2 out. Nice and clean. I can't wait till I get my gear this week. I will be photo documenting all of this to aid others.

Also, I will connect the dots and make 3 circuit lines. The far left & far right I will connect all of the 0's down from the regulator line. The middle one I will solder all the 0's up from the regulator line. And connect my wires all at the "<" locations. Hard to write it without pictures.

 

Sounds like a great idea! Got Part #'s?

 

One of these:

1-Multi Purpose PC Board with 417 holes Cost=$1.79
or
2-Dual General Purpose IC Board Cost=$2.29

I prefer the first. And you can cut this to the size you want.

And then you can enclose it with this:

Project Enclosure 3" x 2" x 1"Cost=$2.29

And lastly you will need:
The 5v regulator Cost=$1.59

You really don't need the enclosure. I guess its over kill a bit. I guess you could just electric tape it. But knowing it is not clean would bug me. And if you ever need to replace the regulator, it makes it easier. That is just me. I am a bit **** I guess. But I want what I want! Total cost with an enclosure and regulator with board is under $7 easy. That's a meal.
