How serious are these cracked welds?

The trailer were talking about is 1995
ABS was not required on trailers until March 1998

 

Truck ABS was required March 1997, you might do some checking. Build date for a 1997 could be late 1996 well into 1997

That would work but by law the dump valve is not supposed to be able to be operated from the drivers seat unless it's not able to be operated above 10 mph. On newer trailers when you spec them new with one they route it through the abs system somehow. So id do an electric switch and chance that the dot man doesn't trace it down through the trailer. With air the just isn't anyway to bluff through that.

Op if it was me I'd run the dump to a separate pigtail. And run 7 wires to the end of the trailer. Never know when you will want to add extras such add back up lights and beacon lights. Also you don't have to buy the expensive yellow cord, use a cheap black one and normal 7 way plugs. Maybe paint the end a different color so when you are hooking up before the first cup of coffee you don't cross them.

 

Yep you should be good.

 

I didn’t realize the trailer or tractor for that matter was that old, it’s probably good to go.

 

I’m assuming you can show me this law.

 

You're fine gumper. Just run it to the centre pin. Should be a blue wire. Maje it switched power with constant power so it always has power regardless of tge key position. Make sure the natural position is aired up that way if you lose power it won't dump the air. A lighted switch is a good idea so you don't flat spot tires by mistake. Btw a lot of older trailer abs pick up power off the brake light circuit. One last thing most trucks have power on two terminals for the tailights. Thats why some trucks have two taillight switches in the dash. You can tie them together and go off one switch. Then you have a terminal for another switched power in a standard 7 pin plug. Back up light, work light, abs. Lift axle ? Repair looks good.

 

That's off a green cord. I don't carry a yellow. Center pin switch on for power, switch off no power. Factory wiring
