First off i cant take complete credit for this, it is on a different forum but it took me awhile to find so I made my own as well. The purpose of this is to slow down the flash rate so sequential lights are more noticeable. This isn't that hard and is much cheaper, $1.60 after tax, than the $30 + modified relays that other places sell.
You'll need a few things to do this:
1 uf capacitor from radio shack, this will get you about 62 flashes per minute
OR 4.7 uf capacitor, this will drop flashes down to about 55 flashes per minute, was a little to slow for my taste
soldering iron
solder
small screw driver
needle nose pliers

Capacitor
I used part number 272-996 from radio shack

The 4.7 uf capacitor is in the same drawer if you choose to go that route

Flasher relay
Located under the driver side dash in a yellow case attached to the fuse panel

Once out you need to get the relay out of the yellow casing, i used a small flat blade screwdriver separating on the alignment pegs and using a needle nose vice grip pliers to pull up. You can see along the one side where i cracked it, don't to that.

Once out the relay should look something like this.

Now you're going to want to take the capacitor you bought and snip the leads a little over half off and bend the ends around forming a little "U".

These "U"s are going to get latched around each side of the 3.3 uF capacitor already on the relay and get soldered creating a 4.3 uF capacitor.

If you wanted an even slower flash rate with the 4.7 uF capacitor then you would cut off the 3.3 uF and solder in just the 4.7 uF capacitor.

Now you can plug the relay back in the car without the yellow cover to test that everything works as it should. Make sure the car is running or you won't get proper voltage and strange things will happen. If everything seems to be working as it should you can throw the yellow cover back on and install back on the clip attached to the fuse block.

Here is a before video showing how the last flasher is not very noticeable with the stock flasher.

This shows what it should look like after the modification, notice the last bulb fully lighting up. With the 4.7 uF flasher the light has more of a pause and it just seemed weird to me so i went this route.

Now go use the $30 you saved to grab a beer :beer:

Thanks, itsnissan daytona blue, needs a repaint though. Has a couple spots where its chipping off cause it wasn't prepped properly

Very clever mod.

I just have a couple of nits to add.

If you can't find a non-polarized cap, make sure you note the polarity of the cap already in the circuit and orient the new cap the same way. If the existing cap is non polarized, make sure you have the "-" sign on the ground side of the circuit.

The cap's voltage rating is important. I couldn't see from the photo if it is 50V (looks like it is) but you should match or exceed the voltage of the stock cap.

I would never have thought of this mod. Great idea.

Dang. Got mine apart and it looks completely different and already had a 4.7uf in it.

Maybe I can find my old stock one.
