pulsed to steady output

i am using this diagram to hook up some lights to use them as intersection lights. i am confused about the coil i see on the +12v turn signal, does it belong there or no?

the ground that comes off the capcitor and resistor, does this goto the body or the ground for the added light? the same with the 2nd ground coming off 85.

i read another thread where it said using a 47uf would only give about 2 seconds, is this true, as i read elsewhere that a 10uf would give 2 seconds?

can the ground of the res. and cap. be twisted together or do they have to have a sepereate contact point on the ground wire?

i am asking alot of questions as this is new to me and im still learning this. thank for any help.

Yes the 12 volt feed from the blinker needs to be there.  That is what tells the device to turn on.  The pulses from the blinker charges the capacitor and it keeps the relay energized while the blinker lamp is off.  Then the next pulse comes around and  charges the cap again.

Ground is ground it does not matter where you ground terminal 85, if you ground it to the lamp, you must also ground the lamp to the chassis of the car too.

The capacitor in this diagram is a 10,000 microfarad capacitor.  Notice the K in 10K uf

Ground is ground, it does not matter if you twist the cap and resistor together and ground both together, or ground each one separately, it does not matter.

What are intersetion lights?

i got that. is that a coil on the wire before the cap? i went radio shack today and all the caps said the number and uf, the store rep said they were all k's, is this incorrect? do the cap and the res. have to match in number? a intersection light is the light in the bumper that lights steady when you turn on your turn signal to light the turn, as in the pic.

ah thanks. 2 more questions, will a 1 amp diode cover any size res. and cap. i use?

all they had was a 60a relay is that excessive, can i go with something smaller?
