flat tow wiring question

[karlbenz]

I'm wanting to flat tow my 64 GMC. Will it hurt anything to splice into the wires at the firewall? All the kits I see are running new wires back. No, I'm not buying a kit. Was looking at them for reference

Thanks

I wouldn't recommend "splicing into" the wiring harness.. I suggest you buy a trailer wiring kit that includes the lights. Fasten the harness along the side of the truck and fasten (clamp, bolt, zip tie) the lights to the rear bumper.. Plug the tow harness into a trailer receptacle on the rear of the towing vehicle, just as you would if towing a trailer.

I'll add this as an after-thought. Disconnect the driveshaft from the differential or you'll wind up with a damaged transmission.

And if you don't mind spending more, they also have wireless tow lights

I’d be worried about losing them. Like the idea though
