Ok I got this sweet old Craftsman 11312130 motor that has the cap start on it. I want to wire a DPDT switch to run both directions. The sticker on the motor says switch the red n black terminals to reverse. How would I wire that to the switch. First pic is CCWR and second pic is CWR
The incoming power on the right is the wire nuts to the two right side terminals. The left side terminals are the ones I switched to reverse. The test works. Now to install the switch. Thank you!!

I tired wiring it like that and the motor spins, but slowly? the only way it reverses and runs full power is for me to switch the red and black wires on those left two terminals. but they have to be connected.. Is one of them neutral and the other ground? Do I still have to keep the right two terminals connected to the hot/neutral? help

Figured it out!!!! I had to get a 3PDT on-off-on switch. Down position is mill on normal. Middle off and up position is mill reversed. Here's what I did
