| Hi, I'm trying to fit a 90s ford stereo to my 1985 Escort. At the moment mine has a live, Earth , speaker and antenor (as I remember) and this has a lot more. It has two plugs with what look like speaker cables on a yellow connector and a black conector block with 6 wires on it. I'm not sure how I'd wire these to my simple cars wiring? Any ideas or diagrams for someone with simple electronics knowlage are welcome Thanks, Chris Here's the block I'm unsure about These are speakers I guess? | |

| Chris, Going by memory the yellow connector is purely for 4 speakers, each corner with a different colour tracer. For example Yellow/Black plus White/Black will be one speaker. Green/White and Green/Yellow another and so on. The other block will be nice and simple too. The large Brown should be your earth. The Red and the Yellow will be permanent positive and ignition positive although I forget which way round. If you wire it wrong it won't remember radio stations when switched off. The others are outputs, so one could be a signal wire for electric antenna. Best thing to do is purely use the Earth, IGN positive and Permanent positive. The others may well be surplus to requirements. Remember though, any unused wire should be insulated off. Hope that helps. | |

| One of the remaining wires will be an electric aerial feed and the other will be illumination/dimmer. | |

| Brown - earth speaker are paired by the trace colour and white is live yellow neg ect (could be the other way round but as long as they are all the same it doesn't seem to matter) | |

| People would probably disagree with me here, but to save your loom in your car and to keep the car futureproof I would be tempted to get an 80s Ford to ISO block connector and then an ISO to '90s Ford connector (I have a few spare now It could just be me but bar the 205 most other Retros I have had have almost always required me to wire in an ISO block because the connector installed which has made a 5 minute job become a longer and more tedious affair (I lived in the Porsche for a month with no radio as a result (as the thread shows)) | |

. OK it will be a ballache now but IME it will make things way easier in the future should you need to swap about HUs for whatever reason (HU packs up, you need to sell it and fit a cheapo for the new owner, you wish to try a HU with new features.| retroturbo Posts: 839 | retroturbo |

| If the loom is original, then I'd go with what ChasR says. You can pick the adaptors up for about £4 each or so off of ebay. The loom is original in my Metro so to fit an elderly Alpine pullout stereo I got an aftermarket loom connector to ISO blocks from ebay (Halfords were even clearing them out at about £3 apiece), cut off the ISO blocks and spliced together the same colours etc up to the wires from the head unit. | |

| That's what I've done on my '81 924, wired up a connector to the existing loom...then I can swap and as I I like....plug and play, I'm bit of a retro stereo perv, so it just makes it easy to swap and change | |

| This is the wiring in my car right now. Just the blue (which i can get in the new wiring harness) and yellow for live, Black for earth and orange. Just looking to find these in the new wiring. Also added a pic of my focus with my original radio in for comic value. I | |

| So i tried this and it didnt work.... I used the power plug from the first 90s ford deck and wired it up to what i thought would be the right wires in the ISO block... it didnt do anything... so either i'm wrong, the colours don't coraspond with the second deck that i'm using... or that deck is dead :/ Any help guys??? | |

| Haven't seen one of these for many years but if memory serves me correctly........ Look at the back of the unit, above the socket for the connector you have there are two more sockets. Each has a round pin and a flat pin. These are the speaker terminals and use speaker DIN connectors. Looking at the rear of the unit and the connector at the bottom, the terminal on the outside right is battery negative. The next one in is battery positive. The other two will be electric aerial and fascia illumination (can't remember which way round though. It doesn't look like the connector block you have is the right one for the unit. Can you post a picture of the back of the radio without the connector in it just so that I can confirm what I have told you. | |

| Hey squonk, This is the back of the stereo. I think i know what you mean as i do have older Ford radios. The plug ive showed connected to the ISO block is from a similar radio (bar TA and Dolby N/R) so i used that plug as some of the forum members had helped out with the colours for that plug... although i tried that first ford radio today and it didnt works... so i must have something completely wrong. The other photos bellow are the back of Radio #2 (the one i want to work) and its original power socket that has completely different colour wiring... and picture 3, my ISO block. | |

| Sorry, got confused there, I thought it was the RST21P that you were trying to wire in! Ignore what I said. What is the model number of the one you are wanting to fit? | |

| Ok, so i tried again and still no luck. I must be doing something stupid. I followed the diagram with the labeled pins (also looked for some more on google to compare) and the solderd up to what seems to be the corresponding wires in my car. Using the block that came out the Mondeo now: Pin1 (Orange/Black) to Yellow My only thought it this ISO block isnt matching up with my ISO in the car... Although a quick check seemed like the ignition colour and battery live are the wrong way around but thats its. I'll check this when i get 5 but i'm guessing its what i'm wiring up to. Could do with a spare battery to check really. | |

| FWIW in 80's stuff the main colour coding was usually; Red- switched live Weirdly on VW /Audi/Porsche of the period the iso connectors meant the perm' live and switched live were the wrong way round in the car so if you didn't know you kept losing the station memory in the radio, proper pita. | |
