NOT for use with Shaker 500 ampIt's a fine harness for what it is but unfortunately for me it's what it isn't that was disappointing. I purchased this harness to wire my Boss aftermarket head unit in a 2006 Ford Mustang GT with the Ford Shaker 500 sound system. This harness does NOT connect an after market head unit to the Shaker amp contrary to what another reviewer stated. I'm giving the product a three star rating due to an unclear product description which led me to purchasing this item when what I actually needed was this: PAC C2R-FRD1 Radio Replacement for Select 2005-up CAN-bus Ford, Lincoln and Mercury Vehicles https://www.amazon.com/dp/B0015ASMIQ/ref=cm_sw_r_fm_apa_VH5.zb4WD0Q6R. 3Works well, BUTI used this in an '06 Mustang GT. It was easy to wire up, everything was labeled nicely and wiring is good quality. If you have an amp, there are a couple extra items you may need. First is a 12v to 5v voltage converter, this just gets tied into the amp out (blue/white), otherwise you may get popping sounds with On/Off. The second in my case, I needed to add a line out converter from the RCA. This allows me to adjust the gain. Initially I wired this up without it and the sound was terrible, way too much volume sound coming from the amped speakers. I emailed their tech support a few times, they were helpful but ultimately the manufacturer of the head unit I bought recommended the solution. Otherwise it works as intended. 4Must rewire adapter for 2012 F250 Ford Factory Sub !I bought this adapter to retain the Ford OEM Subwoofer after changing the factory head unit to an aftermarket Head Unit. I only bought it for the smaller "8 pin" Sub adapter (I knew the larger adapter was not compatible, but the price was reasonable, even for just the small sub adapter).The good news is that the plastic shell mates with the factory sub connector. The bad news is that only two of the 4 wires on the adapter lined up with the corresponding wires on the factory sub connector. So I had to relocate two of the 4 wires (and the two shield wires for the RCA cables had to be removed from the adapter, soldered together, and combined into pin 3 of the adapter). Considering I could not find a suitable "exact fit" adapter (or the wiring diagram, from Metra, or anywhere else), it did "fit" the 2012 F250 factory sub connector, and does work (as long as you are willing and able to rewire the adapter). 2DO NOT BUY FROM AMAZONDo Not Buy this product from Amazon. Ford did what appears to be a mid production shift on a lot of their vehicles, meaning that for some of the same years, it could be either this harness or the Metra 70-5517. Given that this product is "Not Returnable" and does not list that clearly anywhere on the page. It is just not worth the risk. If Amazon is not going to properly index or stand by their products for car stereos, you are much better off getting it from Walmart or Crutchfield, or anyone else who actually knows what they are talking about. 1Buy a different brand this is a hassle.It worked but there are major drawbacks. The wires generally match up with stereo harness some colors are off. They are not tagged. There description is printed on the wire. Problem is some are very faint. RCA harness 2 blue connections not labeled at all. Once I connected stereo I had one speaker not working. I checked all connections. Checked stereo balance. All correct after troubleshooting and alot of fustration I found that issue was connection to harness was bad. The prong was loose. Once pressed in it was still loose. After crimping all connections it was to much a pain to cut all wires. Return harness and redo all this. I used a hot glue gun to secure it. It worked but I would recommend not buying this harness it's to much if a hassle 2Not Correct , No Returns, Don t Buy!I bought this harness for my 2004 Mercury Grand Marquis which the description says it s compatible with. Both plugs fit but neither are pinned correctly. The subwoofer RCA plug pins don t match the positions of the ones in my car s factory harness and the packaging doesn t tell you what any of the wires are for with this harness. The main harness is off by a few pins that don t match up with the other factory harness. I was surprised Amazon isn t accepting returns on an item they sell. 1Wrong WiresIt doesn't have the right wires installed. The connector fits my 2008 Ford F-150 perfectly so no problem with that. The issue I have is the wires on this adapter don't align with the wires on my truck. For example, my truck uses pin #3 for illumination (so the stereo dims at night), but this harness doesn't have a wire in pin #3. My truck doesn't use pin #4, but this harness has a wire in pin #4. Some other examples are my truck uses pins 14, 15, 18, 19, 20 but this connector doesn't have wires in these pins. Altogether this harness has 9 wires correct and 6 wires wrong which is a complete failure in my book. I wish they just stuck a wire in each of the 24 pins then I could use the ones I need and ignore the others (add 10 cents to the cost to make up for the extra materials...). Instead I either have to return this and take my chances on another harness or do what I'm going to do which is move wires around (a pain in the ass because they don't come out of the connector easy) and buy some wire and connectors for the 5 missing wires. Or I could ignore the harness and cut the one off my truck then just twist all the wire pairs together. Regardless of what I end up doing I'm very disappointed in this and even if I return it I've wasted time waiting for it and screwing around with it. Frustrating! 1Did not work on 2003 Lincoln Navigator with amplified Stereo/Navigation unit.All this Harness was able to do was provide power but NO sound out from a new Pioneer AVH-X2600BT. This am connector would not fit the OEM integrated amp connectors. I ended up not even using this Harness. I ended up just cutting and taping into the correct factory power wires. I Made 4 RCA cables for the 2 front and 2 rear speakers plus I made 1 RCA cable to feed the OEM sub-woofer inputs. I cut the OEM amp feed in harness lines and tapped my RCA's to the correct channel inputs. Everything worked fine and I had no need for this harness kit. This was the closes kit Metra had for my install and it did not work. I did use a vehicle specific stereo wiring diagram to locate all the correct wires. 1Had to buy two for steering wheel controlsGreat product. I've had my new deck installed successfully with this product since Jan 2016, but my steering wheel controls did not work. Be aware that this harness doesn't have pins/wires in every hole. For my Ford, you need Pin 18 to install the ASCW-1 unit into. I ended up not using my ASWC-1 from Jan-May, and I finally decided to get it going again. Since I did not want to harm any factory wires in any way (Metra suggested cutting insulation back on the factory wire and taping the SWC wire to it), I opted to buy a second harness, and remove a pin and wire from it to install into my existing harness. For $5 more, it's not a bad option but Metra really should include an additional wire or two with it for folks with Steering Wheel Controls. There's a Youtube video about it, but it's a lot easier than it looks. You remove the red piece inside the harness, push the tan plastic down under the pin, and that frees it. Then you take the your actual harness, locate the needed pin slot (18 in my case, 20 was marked so it was easy to find) and just push it right in until it clicks. I really wish I would I would have read about this before starting my install. This method will give you a wire to solder or connect your steering wheel control module to. For Ford, it's the green/white wire. I'm the sorta person who will spend way more time and money to do a job the right way, so that's why I bought two. I really hope this helps! Enjoy! 5Does not fit Shaker 500.Im sure this is a good wiring harness for a car it fits but not all the wires were correct for the Mustang "Shaker 500", but was not a deal breaker, I worked around it. Maybe put in the description that this will not work 100% for the Shaker systems to keep someone from buying who may not know how to reslove issues with the AC wire, the dimmer wire and the amp wire not being correct. Other then that, eveything else worked. 3
