Could sombody post a link to the headlight relay mod writeup? Yes i did search...

 

what one are you refering to? this is the one for the sport quad beam...there is a cupple headlight mods on this thred https://dodgeforum.com/m_334375/tm.htm

First get a relay and some wire
Second hook post 30 on the realy to the positive termnal on the battry fused at 20 amps
Third hook post 85 of the relay to a good ground
Fourth splice 86 into high beam
Fith splice 87 into low beam

 

Yeah but i'm looking more on what colors the wires are and where the best place to splice into them is.

 

Here is for the headlight switch....see if this is what you want

Here it is incase anyone else wants to do it: (remember this is from DieselDemon and he deserves the credit)

Ok Brad, according to my 95' sm, your headlight wires may be violet w/white stripe for lowbeams....and red w/orange stripe.

You can check the wire colors where the harness plugs into the bulb itself. Now you will have to find these wires in the large bundle as it exits thru the firewall. Try to stay somewhere between the center of the wheel well, and the firewall as the place to dig into the wires to find the two you need.

After you located these two wires, BEFORE you cut them, double check they are correct. Get a 12 test that has the sharp point on it. Clamp the other end to a good ground. Now, take the lowbeam wire, and stick the tester point thru the insulation. Trun the healights on low, and stick the wire again. You should have a lit tester with the headlights on low. Click to highbeam and that tester should go out.

Now find the highbeam wire. Turn the highbeams on, stick the wire, the tester should light up. Now click back to low beams and the tester should go dark.

Ok, you should now have the correct wires. You will have to cut each one. And here we go on the wiring....lol.



Take the LOW BEAM wire coming from the headlight switch in the cab, and hook it to #86 on your relay. Take the HIGH BEAM wire, and hook that to #86 on the second relay. Hook a ground wire to # 85 on BOTH relays, and then attach the other ends to a good ground. You can crimp both grounds together.

Take the LOW BEAM wire going to the headlights, and attach that to #87, on the relay that is being used for low beams.

Take the HIGH BEAM wire going to the headlights and attach that to #87 on the relay being used for high beams.

We're almost done.lol.



Now take 2 seperate lengths of wire. Use 14 gauge or larger. 14 is fine, 12 is better, etc. 10 would be the largest. Hook 2 seperate, FUSED wires from the battery POS, to the #30 on each relay. One wire to each relay.


Install a new headlight switch behind the dash and you're finished.



You're done my man.....lol.

Please let me know if anything confuses you. The trick is good crimps, shrink tubing, and many wraps of GOOD electrical tape. I use Scotch 33 Tartan. Great all wether tape. Use that convoluted wire loom where you can, and make sure the relays are mounted securely. You can even buy a relay "base" with long pigtails on it. Then all you ever have to do is pull out the relay if it goes bad.

And remember, nothing is forever so make sure you carry a spare relay or two. And a few fuses.

Good luck.

 

Is this mod so that both your low and high beams will be on when you click it over to high beam?

 

No Mayfair, this is just to relay the headlights and remove the high current load from the headlight switch. I've read about that high/low simultaneous use. It shortens the bulb life, and weakens the filaments. I installed a set of 80/100's instead. VERY brite setup.


Ok dude, catch ya around.

 

ive been useing the hi/lo mod for over a year now and i dont have sport headlights and its still working good i was worryed about exess heat but so far so good and i usally make 8+ hr trips at night through the mountans with little trafic so there on lots. i also have piaa Xtreme White bulbs 120/95w

 

im not sure of the colours (use a test light or a multi-meter) but i just spliced mine at where the wireing plugs into the bulb, i used solder and heat tubeing than ran the wires to all where i have all my outher realys

 

Can we just sticky this?

 

have a look at this thread https://dodgeforum.com/m_334375/tm.htm there is lots of info in it (it is sticked alredy at the top of 2nd gen)
