Yep, it's 12 volts, capable of 150 amps. It's a little big, but will do the job and there is a wiring diagram included.

Thanks for the info. I may have to go that route if I can't gett this to work. The switch and relays I purchased were from the Deere dealer and on the print for the JD plow. The print showed 2 relays, one switch. I spoke with one of the technicians very briefly about trying to get a schematic and he said wire it with a 3 way switch in a house in mind. All of the prints they have are on a computer and he didn't have the ability to print.

Take a look at my photo #6, I drew this up quick, this may help you. Notice the 2 relays each use 2 normally open contacts. I would put a auto reset circuit breaker in the line that feeds this. Don't know how big the motor is or how much power it draws. In the up mode, the + is connected to the bottom of the motor and the ground connected to the top. Down, the + is connected to top of the motor and the ground to the bottom of the motor. As you can see if you move the switch from up to down too fast the relays may overlap control and flash over.

I've added a photo 7, which will work using the relays you have. It will work, but has a high potential for flash over. The Red arrows would indicate the current flow for UP. The green arrows would indicate current flow for DOWN. I didn't understand your numbering for the contacts on you relays, but they are what is referred to as a form "C". If you can look inside the relay, the moving contact would be the terminal that goes to the motor leads. The normally closed and normally opens should be wired like shown. If you get it wrong the motor may run all the time or not at all. Be sure to use an auto reset automotive circuit breaker in the hot lead. There is nothing worse than having the parts and not being able to get it to work. I’m currently building a 300 PSI PTO driven tree sprayer and adding hydraulic tilt to my snow blower chute. G'day

Thanks for the help! You are right that there is nothing worse to have the parts and can't get something to work! Well, today I was able to confer with a electrician and told him what I wanted to do. He scratched hi noggin, then began dawing. I whipped out your print and he said " thats it!" He told me what leads to hook where etc. I got home, follwed your print and wired it up. It works great! I can't thank all of those that helped me enough; thanks for taking the time from your schedule to help a stranger! If I can repay the advice some time I certainly will.
