Recently burnt out the switch and plug beside the dash surround for my headlights, (low beam, park lights) so I wired in a new plug, and switch and it all works, but to prevent this I want to wire in a relay to switch the low beam load, even though it's less then factory because of the plug in HID system, (unsure of the brand as I brought with them in)

Any help or opinions would be appreciated cheers

Easy enough. Wire the coil of the relay to the existing wires at the ballast (wherever the stock wires are) and then run a wire from the battery to the relay, to the +ive connection for the HID's (put an inline fuse in before the ballast) then the -ive connection straight to chassis/ground

Id use 2 relays (1 for each light) and rated at 30amps or so. You can use 1 relay for both but itd be better to use 2 if you dont want to burn anything else out. You can get proper headlight relays that actually have blade fuses in them but 2 standard relays should be fine. The HID side should be wired to the normally open side of the relay

I use separate circuits for low and high beams. I have a third relay + diodes that acts as a low beam anti flasher. Not too hard to wire up. Make sure you use thicker gauge wiring. I used the driver's side headlight plugs for the triggers.

You won't believe the difference it makes until you see for yourself. Relatively cheap to knock together as well (cheaper than a tune! No point having a powerful car when you can't see at night :P).

Id say its the same as my idea. You dont need to run it all the way from the switch because you can pick it up where it joins the headlight. Because there is such a small amount of current through the relay coil to activate the relay, you wont put anywhere near as much load on the switch etc

    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
