just bringing this question up again .. 

I am still toiling if I wanna make my own harness or not.. I mean 50 bucks.. lol .. its money .. relays are cheap I found some on amazon.. I didnt get the idea of why use the diode in that diagram ? 
I already have an order placed on 30 and 40 amp relays.. I was gonna have to do something for my tach anywaz.. I am putting a new fuse box directly powered from the battery to keep things safe now.. switching it with a relay.. 

I am seeing this relay thing is pretty easy. SO I can build it  .. 

CJ Pony Parts has 20% off headights. Your best bet is to use  relay operated sealed beam halogens, inexpensive set up yet functional.

BUT what headlights to buy people.. my options are listed in a post above. Those are my ranges.. I cant go higher than that.. So please help me pick

Thanks

If the diodes you speak of are on the relay coils, they are to help protect the switch.
By the way, did moving the place where you get positive for the tach fix your problem. I was hoping you didn’t smash a new tach

 

Get this one.
You are on your own on how to get to the nearest NAPA store.

The Ron Francis link also provided previously by Mark in this thread http://www.ronfrancis.com/prodinfo.asp?number=HR-58  shows a relay setup for roughly $56 which is a lot more "painless".  Hard to beat when you look at the time you will invest to put it all together.  They have kits for single headlights (2 total) and quads so a quick phone call to them will determine the correct part to order.  The wire sizes that they would supply will be correct for the application to eliminate the guesswork.

What diodes in what diagram are you asking about. The only diodes I know of in the headlight circuit are the ones across the relay coils to protect the head light switch. You can place these diodes across the relay coils your self or buy relays with diodes built in. If there is some other diodes you are asking about please explain.

Yeah those diodes. I dont know if these have them inbuilt or not. This the relay and harness  I just bought. :: Amazon

If not. Then I guess I will be soldering those on. I gotta go to frys and buy them .. 



AS far as the other harness was concerned. I do like the idea of DIY ... esp the fact that I control what goes down.. :D I am not an expert but I guess this is how I will be a step closer  

I just bought a 50foot of 10 gauge.. and already have some 12 gauge and 14 gauge wire. Have the relays and the connector assortment. I am first going to start with the relay mod on my  original lights. See how that pans out .. If they both work on all circuits, then I will be ordering the halogens. 

I am also doing a relay install for the auxillary fuse box. That is for my other issue (TACH ).. Once that is done, I wil also move my radio from direct from the battery to the aux fuse box. If I succeed, I dont think it should be so hard. But if That all works out. Then next will be this project. While my wiring might not lok as neat as y'all's .. All covered with electrical tape and everything. Lol.. I'll try to tuck it in as best I can. 

I'll keep y'all updated. 

speedway motors has a harness kit.

here is the link:http://www.speedwaymotors.com/Headlight-Relay-Harness-Kit,58825.html

I drew this up a couple hundred years ago.  It is very simple to do it yoursefl with $4 worth of wire and some FORD or BOSCH relays.  I would have concern about using the Chinese relays.

  .....Do you think I need to run new wires for powering the lights from the relays to the bulbs..?.....

I sure would.  I think the factory wires are only 16 ga and they are old.  I ran new 12 ga wires, including grounds, on mine.  But, then again, I am running 90/100 watt bulbs.

This is a another reason I back fed my system.  I didn't want to butcher the factory wiring harness then abandon the wires, forward to the headlights.  I let the unmolested factory wires carry the signal from the switch to the relays, then made a seperate 12 ga harness back out to the headlights.

They are separate bulbs and they do accomodate the standard sealed beam plugs. Not sure about the variations on the bulbs.  I think at least a couple of them are identical with different designations.

Gaba.........we have a guy on here Mr. Tim  who gave me a heckuva deal on a pair of halogen headlamps with the bulbs! Ask him what they were for(car/bike/tractor?) I'd like to know also because if the bulb ever burns out......I need to know the replacement number!

you will have to contact him via email or phone as he is no longer a member here.  Not sure if reads this forum or not.  Sal, email me and I'll send you his phone number or email addy!!  ooops I mean address sorry Word POPO!!

Gaba, Bosch makes relays with the diodes built in I think mine were from a bmw or mercedes
