Guest timn Posted April 13, 2003 Share Posted April 13, 2003 I just installed Cibie replacement headlights. They came with stock 60/50W bulbs. I have some 100/90W bulbs. Can I install these as-is or do I need to add a relay? Anyone using 100/90s with stock wiring? Tim Quote Link to comment Share on other sites More sharing options...
Brad-ManQ45 Posted April 13, 2003 Share Posted April 13, 2003 I think almost everyone on this board who has put in relays would never go back. the headlights are always brighter, and you reduce the load through the switch, which is a major consideration. I would not use higher wattage bulbs without relays, but then again, I would have the relays put in anyway fo rthe above reason. I already have on my 280ZXT, and will on my '75 V8 project.

Cody 82 ZXT Posted April 16, 2003 Share Posted April 16, 2003 I second that..... Quote Link to comment Share on other sites More sharing options...
Tim240z Posted April 16, 2003 Share Posted April 16, 2003 It doesn't make sense not to put relays in. It's 5 bucks and 5 minutes to do!! Not doing it is definitely false economy!! Tim Quote Link to comment Share on other sites More sharing options...

Tim I'm still getting my feet wet on the Z, I just got. Is this a standard 4 prong relay? That is mounted between the switch and battery? or switch and lights?

Tim240z Posted April 19, 2003 Share Posted April 19, 2003 Three or four 'prong' relay....doesn't ,matter which one. Do yourself a huge favour and get a catalogue from Waytek Wire ( http://www.waytekwire.com/ ) Tim Quote Link to comment Share on other sites More sharing options...

innerware Posted April 19, 2003 Share Posted April 19, 2003 I didn't understand. The relay goes where? And does what? Thanks Quote Link to comment Share on other sites More sharing options...
Tim240z Posted April 19, 2003 Share Posted April 19, 2003 The relay is just a little switch. It has (usually) 4 tabs (elec. connectors) on it. 1> Battery positive (directly from battery source) 2> Positive output to the accessory (headlights in this case) 3> Switch positive 4> ground (earth) In relaxed mode the relay is open (no current going to the access.) When you provide current from the switch (headlight switch in this case), it closes the contacts on the relay allowing juice to the lights (full battery juice). The advantage to the relay use is that the power going through the switch is minimal. It only takes a very low amperage to close the relay. Thus, the lights (or other accessories) get full juice without burning out the switch. Stock early Z headlights don't draw that much amperage so it's not THAT big of a deal. Although, by putting in a relay, even with the stock lights, the lights will shine brighter, because you can give 'em more juice and not worry about the switch burning up. Here is a good article if you need more detail: http://electronics.howstuffworks.com/framed.htm?parent=relay.htm&url=http://www.teamrocs.com/technical/pages/relay_basics.htm Hope this helps.

Gollum Posted October 14, 2004 Share Posted October 14, 2004 I'm just a little confused. Would a relay replace the stock headlight switch, or would the relay itself have a switch that you would mount? Quote Link to comment Share on other sites More sharing options...

CruxGNZ Posted October 14, 2004 Share Posted October 14, 2004 I'm just a little confused. Would a relay replace the stock headlight switch, or would the relay itself have a switch that you would mount? The stock headlight switch will turn on the relay, which will then turn on your headlights. EDIT: Look at this link here and you will have a better understanding of how a relay works. You could check out the link that Owen posted, but then you might think a relay is a bunch of naked chicks doin' it. !M! Quote Link to comment Share on other sites More sharing options...

Can I install these as-is or do I need to add a relay? Anyone using 100/90s with stock wiring? Tim Here's an option being offered on the Classic Z Car site. I haven't ordered one yet, but it sounds simple enough, especially for those of us without the background in wiring some of you guys have. http://www.classiczcars.com/forums/showthread.php?p=104111#post104111 Quote Link to comment Share on other sites More sharing options...
innerware Posted October 14, 2004 Share Posted October 14, 2004 check out this link: Im sure most have seen it:http://mywebpages.comcast.net/pparaska/Headlight_Relay_pg1.htm also: http://www.danielsternlighting.com/ I bought my relays through this guy. He was easy to deal with. Haven't installed yet (grad school) but everything is there except for the wire. Quote Link to comment Share on other sites More sharing options...
datsun327 Posted October 14, 2004 Share Posted October 14, 2004 i understand everthing but. do you use 1 relay per light or do you use 1 relay for the both of them. in this case do you "Y" off 1 wire from one of the tabs on the relay?

innerware Posted October 14, 2004 Share Posted October 14, 2004 Hey datsun327 check out the first link in the post above you and scroll down to the bottom, there is a link for a wiring diagram that should answer your question. Quote Link to comment Share on other sites More sharing options...
(goldfish) Posted October 15, 2004 Share Posted October 15, 2004 I was wondering if/how you wire them so the warning red box still works on my zx. I like playing with all the little toys Quote Link to comment Share on other sites More sharing options...
HB280ZT Posted October 19, 2004 Share Posted October 19, 2004 Hi All, So far this has been very interesting, but I came across a cheap solution to your problem . Summit has headlight wiring kits for $40.00. Here are the part numbers: SUM-890035 9005/9006 SUM-890033 H4 SUM-890030 9004 SUM-890031 9007 I hope this helps.
