Batboard

Hello,

I just recently purchased a wildcard box and I was wondering on how to wire it.

I saw the pinout of the DB-25 connector. I have applied Voltage to light the lights.
I know I need relays to use this box since it is only rated for less than an amp per switch.
I am just wondering do I use the N.O contact and the common on the wildcard? Which is the source and which is the output to the relay?
Or is it the otherway around? ie.. N.C. conatct and the common?Also, how to wire the relay as well in conjunction with the contacts and common for the wildcard box.
For your information I will be running 3 LS12's and 2 front grill strobes on four of the switches and will be adding an Airhorn to one of the momentary switches at a later date.
Thank you.

Common is where you supply power to the switch. When the switch is set at the OUT position the connection is N.O. and the N.O. line would be dead until you set to the switch to the IN position. The N.C. will be hot when in the OUT position and dead at the IN position.

So you put power to the commons, run the appropriate wire you want to use (I normally use N.O.) to your relay and there you have it. Attach the appropriate grounds and hot for backlighting and you are finished.

Thanks Jaymz.

Vey helpful.

I have 2 more hopefully final questions.

Can I splice all the commons together at the DB-25 comnector?

Also, Where do I find a 25 wire Cable appropriate for this use? Or if I splice the commons where do I find an 11? wire cable?

Any info on this would help.
Thank you

You can splice the commons together if you wish. Just make sure it's fused properly.. those circuit boards cook real quick when they get too much power. What I did was split out the switches to 4 on one leg and 4 on the other fused at like 2 amps max each.

You may have better luck building your own cable depending on your soldering skills of course. When I built mine each of the 4 switches went to it's own relay box with quick disconnects and all sorts of goodies like that.

It's not the cleanest job I have ever done but it worked like a champ. I'll see if I can find a picture or 2 to post of what I did. What could help is if you can pick up some nice multi colored 22 awg wire to do this with.

Thanks Jaymz.
If you could post a pic or send a pic to me that would be great.
Thanks for the help.
