Trailer Wiring (GM)-whats hot?!

[rotax]

This is on a 98 K1500. I'm trying to rewire my 6 pole (factory installed) trailer connector.

I have a question on where to get a "hot" 12v connection.

There is an orange wire that runs with a blue wire (trailer brake). From what I read, the orange should be a 12v hot, but its not, I'm not sure where, but there is an issue w/ this wire..

So what I'm wondering is if there is ANOTHER 12v hot all the time wire I can tap, I've read "black" is hot as well on GM applications?
I found a bundle of 2 wires, black and white. I'm also under the understanding white is ground, black is hot, by the wiring diagrams I'm looking at.
Both these wires are of guage to support current by the looks of it..

Any info or insight would be greatly appreciated, this wiring stuff has gotten me quite frustrated, and I refuse to take it somewhere and have them tell me ~100-150$ to fix , or rewire something that takes no more than 15 minutes.

Thanks!

The Orange wire is hot but Ive been in this GM world quite a while and there was no factory plug until 1999 on the new body, so more than likely it was never hooked up under the hood below the brake booster should be either taped or zip stripped up those 2 wires. Hook them up and everything should work! Good luck also Black is never HOT on GM...

the orange has/had voltage on and off as i wiggled it and pushed it back n forth etc, thats what is making me assume, somewhere wire is bad...and don't have time/patiance to re trace taht orange to the front of the vehicle.
oh and on another note, my blue wire is hot all the time, is this normal? always 12v on it.. seemed odd, BUT my trailer brakes worked correctly. /boggle?

i'll check under the hood for wiring of the orange nature as well...just in case its something dumb. but, it does have intermittent voltage

thanks for the input!

the brake wire can be powered all the time depending on the brake controller. do you have a led on the controller to indicate there is a circut? if the brakes work dont worry about it. as for the 12v power wire if you get power at times I would check the connections in the plug or it could be the plug its self.

this is with the wire removed from plug. its definately the wire..somewhere.. thinking of running aux off the 'parking lights' wire...this way i can at least get inside lights to work..and charge the battery i wanna put inside.. dunno any other "easy" fixes.

yeah when the trailer is conencted, brake controller has a constant green light. and fades from green to red depending on brake pressure...and setting. so i guess thats fine. least that clears my mind some about that. still hunting for 12v fix.. will putz w/ it more tonight..

Im not trying to insult you...........just wondering if there is a fuse that could be bad....

lol....well wasn't an insult...but yes i'm an idiot. i finally decide...hmm lets look under hood, and boom hey theres that ORANGE wire...so i test it there, no juice...i pull off the cover...check the 2 aux fuses...ones bad...i swap w/ another fuse...oh, theres my 12v! O.O

so problem solved, even tho i felt really stupid and very happy at the same time. hahaha
