How do I add a switch to my marker lights

    I'm retarded when it comes to most things electrical, so any help is appreciated.

    My current set-up has the marker lights plugged into the fuse panel under the dash using the "add-a-circuit" method, just like the picture below.

    I was wondering if someone had some insight on how to get rid of the add a circuit and convert it to a switch?

    Also, any recommendations for a switch I could add to one of the blanks on the dash would be great. Thanks!

    Cut the wire and attach each end of the wire to a switch.

    :rofl:

    The problem I see is that the switches come with like 4 wires hanging off of them.

    I have 2 wires (black and red).

    WTF are the other 2 wires on the switch for and what do I do with them?

    Like I said. Electrical retard here.

    You need to post pic of said switch or diagram. Or what switch you are looking at getting.

    I'm guessing it is a SPDT switch which is why you have 4 leads.

    This is what the business side of the switch looks like.

    I'm guessing the switch is set up to receive a red wire from 2 different accessories, hence the 2 red wires coming off the switch. Is this correct?

    I have already combined the 2 marker lights to run off of 1 red wire earlier in the run, so I would only use 1 red wire from the switch. Right??

    Black is ground......I also have the ground earlier in the run. Does the switch also need to be ground?

    No idea what the green wire is for.

    Green is usually universal for ground.

    So much different options can be done with that wiring all depends on the switch. Do you have a part number or anything?

    Thank you.

    So using this wiring diagram, I have some questions:

    1) Green wire - what would my source be? Are they talking about the battery? Do I have to run a wire from the switch to the battery just to power the switch?
    2) Red 1 - I connect this to the red wire that goes to my accessory - no prob.
    3) Red 2 - Anyone know where the dash light circuit is? Will I find this on the fuse box under the dash? Do I just tap into that wire?
    4) Ground - got it. no prob.

    Green to where your fuse is now.

    Red 2 I'd suggest head light or something that lights up only at night. Or if you don't care about back lighting which is what I believe it is for don't need to hook it up to anything.

    So I'm thinking about purchasing this harness, cutting off their switch and adding my own similar to the ones pictured earlier in the thread.

    Here is what the harness looks like and the wiring diagram. Thoughts? Will this work?

    Don't see why not. Their switch isn't the most pleasant looking.

    Thanks.

    Yeah, I'll cut the switch off and replace with my own.

    Just to close the loop on this thread....I ended up purchasing the wiring harness pictured above, cut the switch off and replaced it with an OEM looking switch.

    Wiring the switch in was a little tricky because none of the colors matched up to the wiring harness (except for black), but I figured it out.

    The only thing that I might change is I wired the blue wire from the switch to an add a fuse. This gives the switch constant power so the lower letters are always illuminated. Then when you engage the switch both the letters and the picture of the lights illuminate.

    I would like to get rid of this add a fuse and tap into the other switches wiring so that the lettering only illuminates when I turn the headlights on.

    Thanks for the advice along the way Dillusion :cheers:
