Radio Question

[170Parker]

As I've said before my mechanical knowledge is limited, and everyone I've asked and everywhere I've looked for this has either no clue what to do, or gives me a different answer than the one before. Trying to replace the stereo in Dad's B2. its a 1989 XLT. The PO cut out the wiring harnesses, and I'm left with this. Assuming this bunch of wires is to the "premium sound" amplifier, but if so how do I hook up my speakers now. Is it just going to be easier to hard wire everything? This has been a b**** and I can't locate any speaker wires anywhere. I pulled the drivers side door speaker to see the wire colors and still no luck.

That looks like cat5 cable, used for internet wiring in a house. Unfortunately I'm not knowledgeable about speaker wiring. Sorry.

Yeah you might be better off wiring it all yourself. Thats what i do when POs mess with stuff. If you havent done wiring before well it will be good practice.

Thats what I would do anyway.

Those cut wires are your speaker wires. There were two plugs on those old radios, one for power and other inputs, one for speakers.

I can't see the colors of the cut wires very well, but the other plug is the power plug, red is power, yellow is memory, blue is a remote wake up, orange is the dimmer, etc.

This makes the other plug the speakers. IIRC there was only one head unit, and so even with the premium sound system it ran the speaker signals to the amp individually. I don't have the book in front of me to verify that, but I'm pretty sure that's how they did it.

Does your Bronco II have the Eddie Bauer package?.

The factory amp is located behind the left rear quarter panel. If you don't want to use it you will need to install a bypass jumper. I would not use the old 89 amp. It will sound like crap, especially with today's "digital" media.

I would just get a new head unit and run all new speaker wires to each speaker. It is a little work to do this but well worth it.

Also look at buying your gear from Crutchfield.

http://www.crutchfield.com

Included with your head unit purchase will be around $50.00 in free installation gear that will make the install so much easier and lifetime customer phone support to help you out. I have been buying from them for more than 20 years. Never a problem.

Here is the wiring for your year.



Constant 12V+ Green/Yellow
Switched 12V+ Yellow/Black
Ground Black
Illumination Blue/Red
Dimmer n/a
Antenna Trigger n/a

Left Front (+) Orange/Green
Left Front (-) Black/White
Right Front (+) White/Green
Right Front (-) Black/White

Left Rear (+) Pink/Green
Left Rear (-) Pink/Blue
Right Rear (+) Pink/Blue
Right Rear (-) Green/Orange

You cannot just hook your new head unit to the speaker wires if the bypass plug is not in the amp. Since the op chopped the harness they might have already put the bypass plug in. You will have to get to the amp to make sure. The amp will not have the plug "pluged in".

When I put in mine a friend separated out the speaker wires through color.In order to figure out which speaker wire went where we use a small battery to the speaker wires and that speaker crackled a little bit.We used a small watch battery not to hurt the speakers.

I changed the radio in my 87 b2 last year , i think my premium sound amp was under a access panel on the top of the dash.
I needed to order a "floating ground adapter" from Crutchfield to get it working correctly with factory wiring.
Also the typical plug and play harnesses on the market did'nt match my wiring so i had to relocate wire in the plug and play harness.
If i remember correctly the floating ground adapter was only needed for the rear speakers.

I just changed mine because the one the previous owner put in bit the dust. With all the cut wires and general mess left by the previous owner I just ran new speaker wires. I was relocating speakers anyway and just wanted a simple head unit that i could have a radio and sync with my phone. I straight wired to the power harness which in my case was already butchered.

You can do the same thing with your multi-meter set on ohms. Connecting and disconnecting will cause the crackle.
