I take it you want to up the rating as well. If you change to H4 bulbs with the same 55/60 (or whatever they are) you shouldn't need relays. I got some Halogen insert headlights straight out of an 80s model Pajero with good bulbs from the wreckers for $25 the pair. Bolted straight into the GQ. Much brighter and that is with the standard rating bulb.

have up graded to h4 on my patrol and fitted same wattage xenon bulbs, have not had to up grade loom or any other components from original, also run rally 4000 hella spotties which i got wired up at a sparky shop with relays fitted and a off on switch, have had this set up for 4 years with many hours of non stop night driving and have had no problems, not even blowing bulbs, my suggestion is to stay with original wattage on globes and fit good quality spotties. There is very little gain from bigger wattage main globes. Col

On the bottom of the relay there are numbers (30 is always battery supply) any spare parts guy who has any idea at all will take five seconds to write down which wire goes to what number. there is only battery, earth , switch and feed wires. some willl feed two lights and some relays only feed one. Your numbers will be 30,85,86,87 the later being the feed (you may find 2) 85 & 86 being earth and switch terminals and 30 is battery. I'm at howesy@optusnet.com.au if you want a diagram but generally you wont need them for a head light upgrade but you most definately will for spotties due to the current draw.

I chucked the sealed beams on my GQ and went to H4s many years ago- ran 100/90 watt bulbs with no problems for a long time, but have now gone to relays for peace of mind- also gets more voltage to the bulb (more light, but bulb will not last as long- it's all a trade off.)

If you only go to standard wattage bulbs (60/55) I would not bother with a relay.
