Bjoern0115 Report post Posted February 5, 2009 Hey all... I've got a 2007 Fusion SE 2.3. I love just about everything about the car, except the rear directional signals. It has the ambiguous sort that are identical to the brake lamp, rather than separate like all European autos. I had the crazy idea this morning to add a second bulb to the reverse lamp fixture and wire that as a directional signal. It would (probably) give the same resistance as the brake lamp, so the flasher shouldn't activate at double-rate. I also figured that the two lamps would rarely be on at the same time, and only for a brief time during a parallel park. I'm a bit worried about the visibility of the directionals, but am sure I can resolve that issue. My only major concern is how to wire it without intruding too much. I know the Milan and Zephyr have amber signals, but I prefer the look of the Fusion, and am wondering if they share a harness for the tail lamp. I haven't had it apart at all yet, blaming the 10-below weather, but this weekend should be warmer, so I can take a look then. So, if anyone knows if the three vehicles share a wiring harness for the rear lamps, your advice would be greatly appreciated. Otherwise, a photo of a Milan or Zephyr harness would be great, so I can play Compare and Contrast. Thanks so much! Quote Share this post Link to post Share on other sites
Bjoern0115 Report post Posted February 5, 2009 I just realised the Milan and Zephyr have LED brake lamps, so I'm not sure whether that would affect my outcome. I'd be using an incandescent indicator bulb, so that should work fine. Right now I'm trying to find a cheap replacement light to experiment with, so if anyone knows a good source, it'd be appreciated. Thanks! Quote Share this post Link to post Share on other sites
Mercury Milan Report post Posted February 5, 2009 My only major concern is how to wire it without intruding too much.You'll need to locate a wiring diagram for the Milan, and work off of that. It will show the harness going to the back leading to a connector. One side of that connector will show you the Fusion wiring, the other will show you how to wire for the Milan. I just realised the Milan and Zephyr have LED brake lampsThe older ones didn't. I'm not sure whether that would affect my outcome.Yes it would. Quote Share this post Link to post Share on other sites
Oblivion Report post Posted February 6, 2009 I think you will be interested in this tread... it eventually talks about the rear taillights. this might be a better approach if you want to change your look. http://www.fordfusionclub.com/index.php?topic=53695.0 :superhero: Quote Share this post Link to post Share on other sites
Bjoern0115 Report post Posted February 8, 2009 At the time, I hadn't really thought it through too well. It was one of those times when there wasn't anything on the radio, so I was on the expressway alone in the silence. Thanks, Oblivion, for the link! I had vague thoughts about the front sidelights, but am still unsure. But the link made it very clear how to work that! I'm just wondering whether rerouting the wiring for the rear indicator will trigger a trouble light for the brake lamp, or if it is even easily done. My Dodge Caravan I wrecked had a tail lamp assembly which detached from the car intact with lamps and plugged into a harness. I installed the European lamps on the back of the van with the amber directionals and red rear fog lamps without too much difficulty, but the wiring looked much different than the Ford's.

From what i recall, the mod description is not talking about rerouting, but shifting the ground wire to force the blinking. Also from what i recall, many cars that have blinking sidelamps are setup with the described wiring setup, hardly a large scale rewiring. Quote Share this post Link to post Share on other sites
Bjoern0115 Report post Posted February 8, 2009 Sorry I wasn't clear on that one. I'm not talking about a major rewiring either. I just meant switching the ground or the lead to add another bulb socket to the reverse lamp housing without eliminating the brake lamps. I'm just wondering how much surgery I would have to perform in order to add another lamp to the tail lamp assembly. The Caravan proved relatively simple, but the Fusion's wiring was never set up to meet European regulations. The sidemarker mod just swapped a ground as I had suspected, but I'm adding another bulb to take over 50% of the function of the brake lamp, and am just wondering if the brake lights and indicators are on one circuit, as they are in the Chevy Impala I also have. That is a leased car, so I wasn't going to try anything with that. The only reason I had to find that (the Impala's circuitry) out was for a ticket I got in addition to an out headlamp. I signaled right when I was pulled over and killed the engine with the indicator still on. The officer added a faulty brake lamp to the ticket and I thought that was impossible; the indicator would have malfunctioned if the bulb was out. I found out if you switch on the signal with the ignition off and brake depressed, the lamp on the side of the signal switched out. I brought a diagram and video to fight the ticket, since the explanation confused everyone. Quote Share this post Link to post Share on other sites
Bjoern0115 Report post Posted February 11, 2009 Hey... I stumbled upon this today. Very similar to what I want to do. I just want to share a housing with the reverse lamp. <object width="425" height="344"><param name="movie" value="http://www.youtube.com/watch?v=nAx2Od5RX2c&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/watch?v=nAx2Od5RX2c&hl=en&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object> Quote Share this post Link to post Share on other sites
