The relay I hooked up has power and a ground. I cut the blue wire (low beams) on the stock harness before the connector that goes to the headlamp, in half. The side that is coming from the harness, I hooked up to one switch of the relay, and the wire going to the female socket (blue, other end of cut wire) to the other switch of the relay.
ok ill try to help, the blue wire is a 12v + wire
the relay may have more than 4 terminals but basicly you have two parts to the relay the switch part which is just like cutting the wire in half and touching it back togeather
and the load part which requires both a positive 12v +
and a negitive- (ground the load portion is what makes and breaks the switch portion of the relay
so that being said: one side of the blue wire that you cut(the one coming from the wireing harness) not the one that goes to the headlight will go to the relay (see the above posts for the number it will be the load portion of the relay, if the relay has a diagram on the side of it the load is the little squiggly line,
the other side of the load (squiggly line) will go to ground -
the other two terminals one will be the other side of the blue wire you cut and the other side will go to another 12v source (battery) and should be fused this needs to also feed the other headlight or this has to be duplicated for the other side
after reading this over it seems confusing to me so ill keep watching the post and try along with the others on here to answer any specific questions good luck :smoker:
ok just went out and grabbed a relay i had #85 goes to ground
#86 blue wire from harness
#30 12v fused from battery
#87 to headlight low beam wire (other side of blue you cut) SORRY TALYN I DIDNT SEE YOUR POST AND LIKE TALYN SAID 87 TO + ON BALLAST (NOT LOW BEAM )
and if they still flicker you can put a capacitor purchased at radioshack inline with the ballast and thats what cured my flicker
