88 xlt radio help

[2 bronco 11s]

What are the plug numbers. I’ll try to find the diagram.

It's OK. More pics will help, and if it's something fixable we'll try to help.

here are some pics I took of the radio I removed yesterday. first is the face. second the part number on the side sticker. third is where I cut them from inside the radio since it was hard wired in from the factory. And the last 2 are the body harness with the clips mine plugged into and then the foam wrapping. I could be wrong about it being factory, but I have been in the auto industry for over 25 years and everything I see makes me believe its factory parts. Let me know your thoughts. thanks.

also I'm thinking since I have 6 speakers its the premium system and that's why things look so different?

These wires are the ones that should match the wiring diagrams

You have a real gem. Family connection, with period documentation is as rare as hen's teeth these days.

Yea, I couldn't believe all the paperwork Bill (father-in-law) kept. Including 2 repaints and 2 timing belts. only has 115k miles, but he was meticulous about care and doing PM. no rust in it at all except a tiny pinhole in roof by one of the drip rails. A little flaking paint in a couple spots. But I'm gonna sand it, prime it and then wrap it in a matte blue. Only reason I got it is my youngest son is turning 16 and wanted Grandads old truck for some reason. Its got a fuel issue keeping it from running I am dealing with. But I am committed to getting it running and safe for him. I already have front and rear shocks, front rotors, calipers, bearings and hoses. Rear drums, shoes, Wheel cylinders and hoses, fuel pumps, fuel tank, fuel filter, fuel injectors and fuel pressure regulator for it. I have the injectors, regulator and high pressure pump installed now. Still gotta install the rest. I figure if I gotta spend 1500 making it safe, that's about what the truck is worth. So I paid 1500for a truck with all new parts essentially. lol

Yea I guess Im gonna have to plug these harnesses back in and then see what colors are plugged into the other side of the body harness to track things. Or just run all new wiring for the radio, but I would prefer not to do that. Im just installing a little digital boss audio radio with bluetooth and new speakers so my son will have a decent stockish sounding radio that works. the stock one had a screen that stopped lighting up and when you turned any of the knobs it would be loud static that sometime would or wouldnt go away depending on the day

no numbers on the plugs I took the pictures of that I removed. only numbers on the ones at the body harness

Thank you for the pictures. Please give me a few to look them over real good.

One comment right away, is that 6 speakers is not from the factory, even with Premium Sound. If memory serves, Rangers with Premium Sound that vintage would have an added "Premium Sound" emblem, on the instrument panel trim piece. Premium Sound added an amplifier, for the rear speakers only, and in first generation trucks it would be mounted high in the center of the dash, below the metal plate next to the windshield.

Does your truck have speakers in the doors?

I'll add some more here after I look over the pics.

That certainly looks like a factory Ford radio. What is unusual, is the wiring colors of the pigtails that you cut from the radio. I'm used to seeing the normal Ford speaker wiring colors, on the older radios with pigtails. Another thing, is I'd have to dig through my stash, but it seems that Ford radios had "Philco" on them somewhere, like on the paper labels. Can't rule out, though, that Ford at times outsourcing some of the radios from third-party suppliers, which would then make sense on the wire colors.

I'm including a wiring diagram for the Premium Sound unit for '88. The plug pin-outs should be all that you need, to wire in the new stereo. I'm sure that your plan, is to use the salvaged pigtails to make an adapter harness for the new radio to the truck's power and speaker plugs. The wire colors on those plugs should match the colors on the schematic.

It sure does sound like an exceptional truck, and it's great that your son has an interest in it. A four-banger auto will make a safe, great first vehicle.

Something worth mentioning, is that I keep a log on all my trucks now. It makes keeping track of maintenance and repairs a lot easier. I bought my first Ranger in 1985, new from the dealer that I did the radio work at. I've only kept a log on my trucks for the last 10 years; I wish that I had started at day one. Two of the recent used trucks that I bought came with receipts from past work; on these two I was able to construct the log before my ownership, pretty much all the way back to "new".

Good luck with your truck!

I thought it had speakers in the doors but, I pulled the cover at the bottom rear of the door and it is actually a vent and not a speaker cover. lol

Believe me, you're not the first nor the only one. That rubber flap is a cab decompression vent, with cab being so small and well sealed. Ford used the same grille as speaker grilles in that era, so it really does look like a speaker.

So I have the speaker side figured out now. I do have a couple questions on the power harness now that we have determined I DO NOT have a premium stereo. So i am gathering the Green/yellow is constant hot and yellow/black is switched power and blue/red is illumination which I believe I wont need since its a new digital head unit? but what about orange/black? is that ground?

 

[TonyLittell]

and also what about the black and pink at the bottom harness pic? Cut and cap them? just like i plan on doing with the illumination wire?

 

[Brain75]

not being an ass, but in post #2 I gave you all that info:
here it is again with a big red highlight.

1 is LG/Y
2 is BK
etc etc

You may not FEEL that you aren't being one, but actually you ARE. I stated that I have very basic wiring at best. Schematics and pin places do nothing for me if I have limited wiring knowledge as I clearly stated. Hence why I asked the questions I did. Questions that were very specific TBH. In the time it took you to pull that Schematic, Edit it, enlarge it to the size you did, explain how you aren't being an ass you could have simply said yes or no to my questions and if I was wrong with my assumption, state which wire was which.

"blue/red is illumination which I believe I wont need since its a new digital head unit? but what about orange/black? is that ground? "

you need illumination (dimmer) unless you want your radio display full 100% brightness all the time, even when it is dark, the headlights are on and you turned the dash illumination down so that it doesn't blind you inside the truck. "Illumination" is dimmer, it is a 0-12v signal that tells the radio how bright it should be displaying the display (in practice I have found it to be 2-12v though).

No it is not ground, it is a 2nd illumination - hence my comment in #4 about ford moving around, marrying or deleting pins. some years it is there some it is not.

pins 2 & 6 are ground (black and black).

"and also what about the black and pink at the bottom harness pic? "

black (pin 6) is ground, some radios only use 2, some only use 6, I would ground both.

pink (pin 7) is not connected to the truck at all (unless you have some premium custom ordered oddball or else someone has redone the radio), I believe it is power retractable antenna, since it is not connected, do what you want with it, cap it / cut it off (makes that wiring connector plug useless for another vehicle).
