As far as I can tell from the pirate tech links and searching the internet, the positive lead goes into the lower left solenoid. Where does the negative cable, (from the battery) go to? I will be wiring it up with 2/0 welding cable.
It's grounded through the mounting, but that is really not a great connection. I prefer a cable, to ensure a good circuit.
I welded a stud (a 5/16" bolt actually) to the back side of the motor case. I was careful to weld it away from a pole piece, so as not to damage a motor coil from the welding heat. It works really well.
I routed the positive cable up from behind, over the top of the motor to the relay box. The ground cable runs with the positive cable and is lugged to the stud on the back of the motor. There is a small factory wire from the relay box to the motor to ensure a good ground at the relay box.

It only takes a few minutes to pull the motor and weld a bolt to the case.
I don't believe that the winches come with a ground cable. At least the old ones didn't (don't know about the 8274-50). Negative (ground) is provided by the structure of the winch and it's mounting to the bumper. You can run a ground wire to one of the motor bolts or to one of the winch mounting bolts. Welding a bolt to the motor case works out better.
I don't know about that winch but my 12000 has a ground to the motor (I'm surprised that yours doesn't). The best place to ground that wire is at the battery. A winch draws alot of current and since the source of the current is the battery, and the load is the motor, that is where you should go. If you merely ground to the frame, all of the resistance between the battery and frame can reduce the perfomance of the winch.
What year is your 8274? Mine is a 1991 and it has a ground lead directly to the battery. On the winch side it attaches to a bolt on the bottom of the motor casing. The solenoid box also has it's own ground that attaches there as well.
I am fairly certain that is an older model, maybe early 80's? The only studs my motor has on it are the three for the cable that go to the solenoid box. Can I use one of those studs or will it screw something up?

I went out and looked at mine. Look on the bottom of the motor casing for a threaded hole. That is where the ground bolts in. The other 3 terminals are not ground terminals. Pretty sure you'll get a short grounding there! You could also ground to one of the support bolts on the back of the motor. Just make sure there is a solid and clean connection. Good luck getting it running.
Well the 8274 is wired up and ready for recovery! I took some pictures to make sure everything looked good to you guys. I want to make sure the cable looks good to insure I don't ruin it on the first real recovery.
By the way my front springs hate me now with the added weight. . .
Tucked in there nice and tight after I modified the mounts . . . 1/8" to spare
I messed with the brackets quite a bit. I have the 4+ shackle reversal so the frame mounts required some modification as well. I filled the original holes and made new ones where they would fit, while trying to get the winch as close as possible to the grill. I'm not sure if all fairleads (sp?) are the same, but the one I had did not match up to the holes in the bumper. So I redrilled news holes in the fairlead and moved it up as far as possible. I'll take some more pictures of what I to the mounting brackets or you can check them out for yourself in the middle of September for yourself
