bump as this is the easiest and perfect way to get rid of headlight flicker with aftermarket units. Venom did a HUGE favor by making this suck much less to figure out. all items are easily found at radio shack.
some hints: using an axial instead of radial capacitor is easier to install. axial has the leads at each end and radial has both leads at one end. using an axial cap allows you to work "in-line" and heat shrink everything easier.
also again the ARROW on the capacitor should go to ground.
and again, the LINE end of the diode goes to the relay.
I found if do all the diode/cap part first then it would be less confusing to a novice.
Like this: connect your new low beam switching wire to the factory wire, cut your new low beam switching wire a few inches after that, solder in the non striped end of the diode to that lead, solder your low beam wire to the striped end of the diode, heat shrink it and move on. repeat for high beam
a couple inches after your "inline" diodes go and strip a 1/4-1/2 patch on your new high/low beam switching wires, wrap the NON ARROW lead of the capacitor around that bare wire (one cap per), solder and seal. then go and strip a patch on your ground wire, twist both arrow leads of the cap together, wrap them around the exposed ground wire, solder and seal.
now you have just your normal wires to work with instead of trying to solder caps/diodes to your relay base
a switching wire for high and low and the ground for the relays
