Honda Civic DIYs and Civic Tech ChatHonda Civic DIYs and Civic Tech Chat - for the true gearheads! Bring your wrench, it's time for some Honda Civic DIY projects! Questions about problems with your car do NOT go here.
I know there are a lot of tutorials on how to make your own CAI's, but i was curious on the specs of an AEM CAI (Like the measurements and stuff i need) so i can do it myself. I drive a 99 civic ex coupe. If you can help thanks!
i dont really like cai and have never owned one, but if it never rains where you are, prolly not a problem. there is really no set shape, you can make whatever fits in the engine bay. alot of people use heat resistant plastic pipe, try not to go too big cause you will lose speed, also make sure it is super smooth inside. try not to make any hard 90 degree bends unless you have to. but theres lots of ways to make your own.
hi. hope you can help me with my messed headlight wiring.
Since i don't know how to retrofit my OEM headlights with projectors, i just bought a higher wattage halogen bulb. After days of studying how to make my own headlight harness, i had finally made my own.
all of the wiring in the harness was ok. 1 relay for the low beam and 1 relay for the hi beam.
85 for ground, 86 for the switch, 30 to battery and 85 to the bulbs.
All the wiring was ok except for 1. I accidentally switched the hi beam wire going to the harness with the ground.
When the harness is installed, the hi beam is activated while i was in the low beam. and when i turn the switch to hi beam, the headlights go off.
now i removed the harness and returned to the oem wiring.
The untouched h4 socket works fine but the one which i attached my harness too was very dim. the h4 bulb's brightness is as equal as my corner lights.
I already checked the fuse box and there were no melted fuse. tried removing the 10amp fuses trying my luck to get the headlights disconnected but it seems that its not the 10amp fuse.
I really need your advice.
Alright gearbox, I have checked the forum and found nothing on this problem/ DIY. If you know where I can find it on here, please post the link, post your own DIY... whatever you can do to help is appreciated. With that being said, I am trying to replace my CV shaft tomorrow. People have tried explaining what needs to be done but honestly I think they're talking out their a$$es since they don't own civics. Are there any special tools I need? I was told there's a huge socket I'm going to need... any idea what size? How about replacement parts other than the shaft. I know that sometimes it is recommended you replace certain nuts, clips, etc. when you remove them. Any special grease or any grease at all that I'm going to need? Sorry for all the questions, but I definitely don't wanna screw this one up. Let me know if you can help me out... Thanks
P.S. My automotive lingo is subpar, so any pics you can provide would be key as well. Also, it's the left side I am working on, and I have an '03 sedan, manual if any of that helps or makes a difference.

for flip flop trunk, i wanna do it too but never found a good diy. im not sure what it involves so ill let you know when i find something.
for the headlights, usually if its really dim, a ground is not working properly or you maybe messed up one of the wires. i would avoid all the extra work trying to figure out which wire got fried and just make (or buy) a good harness and bypass the stock one. suvlights.com i know sells plug and play harness, or just try and make your own again. it seems like you know how to do it, just try again. the wire colors for h4 plugs are here: left side, red/yel is 12v common, red/wht is LO, and red/blu is HI. right side, red is 12v common, red/wht is LO, and red/blu is HI. now let me explain what this means. its a backwards system, meaning that the 12v wire stays hot and provides power when both the lo and hi beam is used. it is like constant power. when only the lo beam is used, the 12v wire is hot, and the LO wire becomes a ground. this allows only the lo beam to stay on. the HI wire becomes hot, thus keeping the hi beam off because it doesnt have a ground. when you flip on the hi beam, 12v wire is hot, and the HI wire becomes a ground so only the hi beams work. the LO wire becomes hot, and keeps the lo beam from working since there is no ground for it.
for cv shafts, its alot of work from what i know. ive never actually done it, but you may need air tools to get that big bolt off. and some force pushing the new axle in. my advice is buy a brand new one (not remanufactured), and it will come with everything ready to install, boots and grease and all. straight swap. now i would recommend the honda manual cause it gives you all the torque values. very important to follow that. and you should be able to reuse the stock hardware unless one of the clips or something is broken. goto advance or kragen to order one if its not is stock. autozone is suck.
they will, you just have to widen one of the bolt holes. three of the four fit perfectly. its a very easy swap and alot of people only use the three bolts. but its not hard to drill out the 4th one so it will line up. otherwise its in the wrong spot by just a lil bit. same for rsx seats (cloth or leather).
03 ex is new style, 04 vp is old style.
