Projects Painless wiring help needed!

Howdy.

I need a little help troubleshooting an electrical problem on my 54 truck.

Here is what I have:

Older Painless universal harness that I had in the truck working perfectly harness #10101 but it is an older one that was new in the box from a swap meet.

I took the truck apart and painted it and added a flaming river corvette type column.

The harness has a molex connector that goes to a gm signal connector that goes to the steering column.

I now have two problems.

I have 12 volts to the tail section wires 948 and 949 left rear and right rear turn signal.

The horn goes off as soon as you put the wire to it.

I like to think that it is something simple. I really don't care about the horn but the turn signal problem is pretty important.

I tried tech support at both flaming river and painless but they were closed.

The steering column was a swap item too but it appeared to be new in the box. I have a 62 chevy impala steering wheel on the column and havn't hooked up any thing to the horn ground.

Thanks for any help.

you hook up the wire for the horn to the column and the horn sounds.
horn*****on stuck/grounded to the column

signal wire to the column need power feed to the signal switch then the switch will send it to the lights.
just not familiar with the wire colour for 62. 9yrs before me.
maybe but not sure test with a test light.
green-right-rear
yellow-left-rear
blue-rf and indicator
light blue-lf and indicator
brown 4-ways hazards
white brakes
black horn ground
purple power feed from flasher

 

Horn goes off when I put the wire to it at the horn. I just have the steering wheel mounted.

Correct. What gets me is the front lights work correctly. I can't figure why just the rear are getting voltage.

 

do the front signals flash with the rear hooked up left or right?
maybe the flasher is too weak for the system.
or signal****embley is shorted/shot

 

Nope.

Here's a shot of the column. You can see the gm type wire connector in this shot it's an old one.



Thanks for your help. It's gotta be something simple.

 

no older than mine.lol

 

That does look old!

 

Is there power to that wire now? If so, it's the power wire to the horn relay, the control circuit will be seperate.

On the other hand, if the horn has power to it, and that's the ground wire, as somebody else has already said, the horn*****on or wire is inadvertently grounded in the column somehow.

 

out of an 88 grand am.
most if not all gm's from 8?to90 used the same signal****embly.
this is a spare. mainly for the cancel springs.
have to pull my column apart to install the wiper switch.

 

12 volts to the horn wire that is marked #924 to horn green wire.

 

the wire you want should be the ground trigger from the horn relay.
sending 12v up to the horn*****on will be instant short to ground.

 

went to painless looked up the kit.
924 is from the horn goes to the relay.
are you using a 3 or 4 pin relay for the horn?

I have the top relay on this drawing/

 

so you have a 4/5 pin relay so 87a is not used.
