Well, I've had my Cefiro 1 piece headlights on for about 4 months and I love the look of them. However, getting them to function properly has been a problem. Originally, one guy helped me put them in and tried to wire the low/high beam lights. This resulted in the highbeam dash light to come on about half power, which told me he wired the lights wrong.

I finally took it to another mechanic (I'm no good with wiring), and he re-wired the headlights. The highbeam light went off, and the headlights were noticably better. However, last night, after only like 2 days of having them fixed, something went wrong. I can get the high beams to work on both sides, but now only the drivers side has a working low beam. What could have caused this?

In addition, my mechanic still can't figure out how to wire the running lights and corner lights. He says its physically impossible to get the stock harness to fit into the Cefiro harness for the corner lights. I even showed him these 3 threads....

but he still can't figure out what to do with the running lights and corner lights. Any help you guys could give me would really help me out. Thanks.

 

For the running lights (or parking lights as it is originally), you have to cut the harness for the parking lights, and wire them up to the running lights... The only problem I found was that the wires are rather short, so trying to reach from the corner to the bottom of the headlight was a hard reach, just barely made it. I recommend splicing in some additional length on those wires so you have some breathing space. Looks real cool with those european (running) lights.

About the wiring, what will probably help are diagrams from the manual, contact me if you need a diagram or two of the wiring. It's not 100% clear from the diagram but generally you can get it in a few tries. (ie/ it says R/G, does that mean red or green)-- if I can find the appendix I'll attach that too. Let me know,

 

BTW- try getting a splicing kit with those red connectors. You can use these to put on the ends of your wires so that you can swap wires easily without resplicing. Get some male and female connectors, put all male connectors and all female connectors on different sides (one type on the harness, one type on the wires from the car). All you do is strip the ends of the wire, put the connector in place, and with the hand splicer thing, you crimp the connector onto the wire so it forms a tight connection. Then you can plug and play till you get it right, then just put some electrical tape to keep the moisture out once you get it.

 

For the headlights. These are the stock wire color and corresponding function.

Left.
Green/yellow is low
yellow is high
Black is ground

Right
Light green/black is high
Blue/Black is low
Black is ground

I think different H4 harness may have different colored wires, I am not sure. But the black will be the ground. Knowing the stock wires and that blacks is ground gives you a 50/50 chance of being right with the high an low.

The stock corner(turn signals) lights must be modified to fit into the cefiro headlights. No, they will not fit. So the tabs must be shaven to fit. Real easy to do. An exacto knife will do just fine.

The city light(smallest one), must be seperated from the corner light. Harness must be cut off and extra wire used to reach the cefiro headlights. Then the harness must be cut of the city light. Connect the corresponding wires.

I really need to do a complete write up on this.

 

Thanks for the tips. Would it be possible for you to somehow send me a pic from the manual?

Mike- Do you have any pics of the cut tabs? I tried to tell my mechanic to cut them, but he had no idea what to do.

 

Not trying to be a d!ck, but why are you paying for this simple job? I am by no means good with electrical things and was able to do it w/o any directions. Before my headlight install the only electrical job I had done was hook up amps and head units.

When I say "cut the tabs" I mean this; obviously the stock corner light will not fit into the opening on the cefiro's. If you look at them closely, the tabs on the stock harness, I believe there are three of them, don't line up with the 3 openings on the cefiro's. An exacto knife needs to be used to cut the plastic on the cefiro's opening in order to accept the stock harness.

The only good analogy I can think of is that it's like trying to fit a square peg in a round hole......... so the round hole must be made square.


Just do it your self. Fool with it long enough and you will see what you need to do.

 

Hi, im new to this forum, and i am just wondering where exactly i can get some cefiro headlights, or cefiro, some help would be greatly appreciated.

Thanks

 

or cefiro parts, sorry about that

 

Well, I think I'm a few steps behind you in terms of electrical ability....I would have no idea how to install a HU. But I guess I will have to try this out. For the running lights, which wire do I seperate from the corner light?

 

In stock form the corner bulb and turn signal bulb are right next to each other. Their wires are bundled up together untill the harness. With the cefiros the corner light(city light) and turn signal are not next to each other. The stock wires are long enough to reach the corner but not the corner light and city light both.

So you must "seperate" the two stock wires as much as possible. If you follow the wires back far enough they connect to another harness. Leave that harness alone. Once you seperate the wires they will still not be long enough tp reach the city light, so additional wire but be used.

That is when you will have to cut off the stock harness. Once you do that you will have two loose wires. What then do you connect those two wires to? Well, the cefiro city light has a harness on the end of it. Obviously you cant connect the two loose wires you just created into that city light harness. This is when you cut off the city light harness. This is a little more difficult to do and it will leave you without much wire to work with. Now once you have both harness cut off you just connect the two loose wires comming from where the stock corner harness used to be and the two loose wires comming from whre the cefiro city light harness used to be.

 

Do you need to buy pigtails?

If so, where do you get them, how much do they cost, and how are they used?

(why do we need them)
