Here are my instructions are making your sidemarkers blink. With this mod, your sidemarkers will blink with your turn signals when parking lights\headlights are OFF. If your parking\headlights are on, then they will blink interchangably (ie, sidemarker on while turn signal off, sidemarker off, while turn signal on).
Before we start, make sure you unscrew your sidemarkers, and just let the bulb hang inside the bumper.
Tools you will need:
10mm head to remove bolts
Philip head screw driver
Electrical tape
Scissors
Knife\wire stripper
Here we go:
Step 1: remove grill --
Remove the grill with the prelude logo on it. Remove the two bolts on the ends of it (10mm). Next, using a flat head screwdriver, pop up the tabs that hold the grill to the frame of the car, so you can pull those out (there will be three of these -- two against the frame, and one in the center connected to the bumper).
Step 2: Unbolt\unscrew bumper --
There will be 3 bolts(maybe more? I forgot...) (also 10mm, like before) underneath the car that secure the bumper and black covering to the rest of the car. There's one in the center, and one on either side of it, spaced about 12inches apart. Removed those 3 (or more) bolts. Next, near each fender well, where the bumper meets the side fenders, there will be a screw (philip head) that you need to remove. After removing those two screws, and the bolts underneath, the bumper is ready to come off.
Now, to remove the bumper, you'll want to do this one side at a time. Take a look at how the bumper is held onto the frame of the car\fender area. What you want to do is, pull out to the side, and towards the front of the car until the side pops out some. Do that on the other side as well. Then go back to the first side you worked on, and pull it all the way, until the bumper starts to come off. This will help if you have one extra person to pull the other side at the same time. Now, don't pull it too far (you need to remove your bulb housing from the turn signals, so they don't pull).
Step 3: wiring --
Now that the bumper is off, you can see the wires that lead to both the turn signals, and the sidemarkers. There will be a black soft plastic piece covering the wires to the sidemarkers. Cut the whole thing off, so you can expose the wires. You'll also want to do this for the turn signals.
For the sidemarkers, you should see 2 wires (one black, and one red). The black wire is what we want to cut. You'll want to cut it so you have 95% of the wire length coming from the end that's connected to the bulb. Leave just a little bit of the black wire still coming out of the other end, so if you ever needed to reconnect it for some reason, you could. With the wire cut, you'll want to strip away some of the black, so you can get the actual copper wire to show. You'll want about 1cm of copper showing.
For the turn signals, you should also see 2 wires (one black, and one another color). We don’t want to cut either of these wires, but we DO want to splice into the POWER wire (the colored one) of the turn signal. Take a knife, and slowly slice away at part of the wire, so you can expose the copper. NOTE: You'll want to do this to as CLOSE as you can to where the sidemarker wires connect to. If you don't, you won't have enough slack to be able to put the bulb back into the sidemarker.
Now that you've cut the sidemarker black wire, and you've spliced an opening in the power wire of the turn signal, just touch the sidemarker wire to the turn signal wire, and hold it there while you have someone turn on your parking lights. The sidemarker should come on. With you still holding the wires in place, have them turn the hazzards on, so the lights will blink. The sidemarker and turn signal should blink interchangably. If things are good to go, secure the wires together as best you can, and cover it up REALLY well with electrical tape.
Repeat the process for the other side.
Step 4: Check connections, and reinstall bumper --
Make sure all connections are secure, and that all bulbs\signals are working properly before you put the bumper back on.
Move the bumper up to the car, and pop your turn signal bulbs back in. Also, slide your sidemarker bulbs through the hole, and hold it there while you install the bumper, so the bulb won't be stuck back there, without you not being able to get to it
Bolt the bumper back up, the grill, and you're done!
I hope the instructions are useable for you. I'm sure you'll be able to do it with no problem. Good luck! And hope all goes well!
------ if this all sounds complicated, it isnt. Basic idea is -- connect the ground wire (black) from the sidemarker bulb to the power wire (red or green) of the turn signal. -------
