I have the relay the switch and all the wiring that went with it. Came out of a 1994 mazda b4000 the guy said he paid 300 $ for it. I got them free lol. Vehicle came in on trade and is going to the junk yard. I might score the wheels and tires off it too.
Why? Ive heard of this before. Ive heard its not the best to run them straight from the battery to the lights. (the way I have it on mine)
Why is that?
Lights usually draw a lot of current. When wired directly to the switch, It can cause the switch to melt,catch on fire,burn the vehicle to the ground, cause the surrounding landscape to go up in flames, burn down whatever building is on that landscape...You get the idea. The relay acts as a buffer between the light and the switch.
OK so my curiosity got the better of me and i removed the screws. The screws hold on the plastic housing and the lights are h3. So later on down the road if a light burns out where do i get them from. And can I put a piaa bulb in it or is the hella bulb the best for the light?
hmm... maybe I should re route mine. Im gettin nervous
Its only an issue if you've deleted the fuse, used too small a wire and/or are running high wattage bulbs. You'll also get a cleaner, higher amperage source of power running off the battery itself and using the relay as the switch point vs using the rocker/toggle switch.
i'd run them straight from the battery and have the relay connected to one of the high-beam wires. might also want to wire an extra switch between the relay and the high-beam wire, so you can turn the hellas off while using high-beams if needed. IMO comes in handy on heavily foggy nights.where i live, the switch is compulsory anyhow. the relay doesn't draw much current either, so the slightly reduced output of the standard high-beams shouldn't be noticeable.
Doesn't running them straight from the switch also result in an high voltage drop due to high resitance?
Bought it, drove it, broke it, fixed it, drove it, broke it again... Love it!
My stock fog lenses fell out, replaced with a set of Hella 550's similar to those. Wired them into the stock harness so they're controlled by the fog switch and relay.
If the wires are there... you could snag a stock switch pod with fog switch from JY or e b a y, then install a fog relay. Relay goes in the PDC. If the relay socket has contacts, then wiring is likely there.
Here are some pics I finally hooked them up last night. My dad suggested I make a new harness so I did. I just have to align them properly now but they seem to do the trick. just waiting for my new lamps to come in not, on the 13th is the estimated time they will arrive.
