I just got the relay to put inline with my headlight. I also got the one for my KC lights. my question is for the headlights do i wire the relay before the dimmer switch or after. the relay has two outputs to lights and i don't know if i have to use both, or just cap one of and run it straight to the dimmer.
Thanks for any help

/wwwthreads_images/icons/crazy.gif Er.....Danny. Does that relay also have two coil inputs? and then one ground wire? Is it made special for headlights? If not, it sounds to me like it is for high beam only. One wire to each high beam, and then the relay coil goes to the high beam lead that is coming FROM the dimmer switch. The relay itself has a separate fused feeder from a good, hot voltage source./wwwthreads_images/icons/crazy.gif I'd send the moonguy/wwwthreads_images/icons/wink.gif/wwwthreads_images/icons/wink.gif/wwwthreads_images/icons/smile.gif crew over to help you but they are still asleep after a Saturday night of......well, you get the idea./wwwthreads_images/icons/crazy.gif

I never believe any statistics unless my moonguys /wwwthreads_images/icons/crazy.gif/wwwthreads_images/icons/wink.gif made 'em up themselves.

Here ya go....from the archives. I don't remember where this post came from. May have been from the old board.


Step 1: Remove all of the butt connectors. These can be used for temporary
fixes, but they create way too much resistance for permanant use, plus
they have a tendancy to come loose at the worst possible time.

Step 2: Solder each connection and insulate - prefferably with a nice
piece of heat shrinkable tubing, if not then good quality electrical
tape (something like 3m super33 - it's more expensive, but way worth
it)

This may be enough to fix your problem, but if you want the ultimate
set-up for off-roading or just even just really bright lights, proceed
to the next steps.

Step 3: Get 2 standard automotive relays and wire them into your existing
headlight harness. Relay 1 will be for your low-beams, relay 2 for
high-beams, and will be connected as follows:
Relay 1: 85> low-beam from switch
86> ground
30> Batt. (go directly to the battery and fuse it within
6")
87A> Not used
87> low-beam to bulb
Relay 2: 85> high-beam from switch
86> ground
30> Same wire as 30 on relay 1
87A> Not used
87> high-beam to bulb

With this set-up, you'll only use the power running through the headlight
switch to power a relay, the current actually running the lamp will
be comming straight from the battery/alternator. This will provide
the maximum possible light from your headlights. It will also allow
you to upgrade headlight bulbs to a higher wattage if desired, without
burning up your switch or the wiring. Use at least 12 gauge wire for
the power supply line running to the battery, do not forget to fuse
it or you may have a jeep-b-que on the trail if the line shorts out
(this is true of ANY wires you run to the battery for lights, stereo,
ANYTHING!!). Also, even though you have 4 different lights (right/left/low/high)
you still only need 2 relays. You can also use the same power supply
line for both relays, so you only need to run 1 wire to the battery,
and use 1 fuse. This set-up is also sold pre-wired and packaged by
Jacobs electronics and called the Jacobs headlight brightner kit. A
buddy of mine bought one and paid about $80 for it. When he got it,
I looked at it, laughed, and duplicated it for about $7 (2 relays, a
few feet of 12g wire, a fuse holder and a fuse). I love it!! Anyway,
though this might help. Let me know how it goes, and happy Jeepin'!

I just got finished doing that to my Scrambler this weekend. The relay goes after the dimmer switch. You need one relay for the high beams and one for the low beams. Only use the second ouput if you want something (light) to come on when that relay switch is activated, or it could be used to go the the other headlight if you're re-wiring the plug too (but it already feeds from left headlight to right anyway).
I found the easiest place to splice in the relay was just behind the left (drivers) headlight, just before it goes into the 3-prong plug-in. Hope that is of some help.

Keep on Jeepin'

i have the relay right in front of me. I am going to do my KC lights first, but now i am stumped. This is a relay i got from auto zone, it is a Baja Tough heavy duty relay.There are five prongs. 1 ground, 2 Outputs to lights, 1 to switching means, and 1 to fused power source. My confusion is that my switch for the KC' is just a plain metal toggle switch. My plan was to run the power from the fuse block to the switch then the switch wire into the relay. Can i not use the connector that goes from the power to relay? And only use the power to relay that comes from my switch? My switch is already prewired. one in, and one out.
Thanks for the help, guys are great.
