headlight mod!!! [1996-97 single beam to 1998-00 dual beam]

[pearlrav4]

Hello fellow RAVERS

I am in the middle of converting my 1997 headlights to dual beam 1998 to 2000 headlights but thing is i am stuck....

I already have the harness from a 1998 dual beam RAV 4 but i dont know how to connect it the my harness which is H4 (and i dont want to cut).

The H4 has three wires and the HB4 / H3 has four in total.

The High beam is red/yellow and red (HB4)

The Low beam is white /black and red (H3)

Can someone tell me were to connect these four wires to the H4 harness?

Thanks

i've done this mod before but i used an adaptor harness which has it's own relays for hi & lo beams. i just spliced the supply for the relays from one of the h4 bulb sockets. i can't remember what the wire colors were and i'd go outside and look if it wasn't for this typhoon blowing over as i type... one of the two wires from each of the h3 & hb4 are ground wires... the h4 bulb has only one ground wire for both hi & lo beam... i tested each wire in the h4 socket with a voltmeter to see which was the hi, lo, & ground.. as i remember on the '98 lights, the outer most lights are the lo & the inner lights are the hi..

hope that helps yah a bit..

Do you have a test light or Voltmeter??

A test light is easy to make up if you dont have one..... (they are cheap enough to buy too...)

-> get yourself a length of wire (About 3 feet is more than enough) cut in half, strip about 1 inch of insulation from each of the ends, connect an appropriate 12 volt light to the wires :


GND < ===== > LIGHT BULB < ===== > CIRCUIT to test


-> Use one end as a ground wire (Wire it to a nut or exposed metal on the body of the car)

-> With the other end, connect to each wire in turn (Turn your headlights on LOW)....

You should only get the light to go on with ONE connector...... IE; the powered circuit.... MARK IT so you dont forget it...

Now put the lights on HIGH BEAM and check the other 2 connectors..... You should now know which is the one for the high beams.... connect these correctly to your new lights and away you go....

Thanks guys!!!!

I will keep you posted.....by the way how did you get your park lights!!!!!since the 97 parklights are in the headlight.i was thinking of drilling a small hole in the dual reflector headlamps and stick them in there using some silicone to keep it water tight.

Tell me what do you guys think?

In my 98 RAV, the park lights are in the bumper below the main beams...... you could also do this mod but you would need a new bumper??? (Not 100% sure on that)

[pearlrav4]

Nah

Replacing the bumper is a definite NO!NO! got some beautiful factory installed bumper extensions.....looks neat..u can visit my profile if u want to...got two pics of my rav.


I am also wondering if i need a relay installed to have the headlight mod work or is there already a relay in place?


Thanks

i changed the front indicator bulb holders for tail/brake type dual filament bulb holders and wired the park lights to the 5 watt filament and the indicators to the 21 watt filaments. then i put roof sealant in the back of the bulb holders to stop water going in!!

now my park lights are orange, but then again, this is the philippines!!!

Thanks

Can you send me some pics as to how you wired the dual lights into the OEM harness?


thanks

ok, i'll see if i have the time..

by the way, the typhoon that passed by us last thursday was a cat 4 (180-220 kph winds) and flood water up to your chin or deeper in some places!! now i have 1st hand experience of what happens when the cai intake goes under water.... it sucks water all the way up to the filter and stalls out big-time!! and it won't start for at least an hour even after wading out and disconnecting the intake duct from the filter and letting the water out!!!!!! hehehe, i'll know to disconnect the duct BEFORE entering the water next time!!!!


another typhoon comming but not so close this time!!

a couple of movies from thursday!!

ok, a couple of pix but not so helpfull i'm afraid! i had already removed the h4 3-wire socket coz it melted and i spliced directly into the relay wiring and then hid it as best i could! same with the park/indicator wiring.... and since i'm here in the office, i don't really want to go digging it out!! anyway, here ya go...


the two relays at the bottom are for the hi/lo beam..

sorry you can't see much!!
