3rd function build

Hey guys need some help with a 3rd function build. After looking over this site and reading what others were doing to save some money on adding a 3rd function I finally have all my parts but I致e run into a somewhat a problem.
I watched a YouTube video (Cal attachments ) and got A lot of info from there the guy was actually installing one on a tractor let mine. I purchased the same pump they were using a D03S-2C-12D-35 and the D03 subplate and fittings from surplus center. I put the motor and subplate together with only 2 screws and mounted it to my bracket just like the guy did on YouTube with the p port on the outside and the t on the side facing inward A port on top B port on the bottom. This morning I starting putting the motor and subplate back together as I did the first time but all 4 bolts bolts that hold the solenoid to the subplate wouldnt line up. I can flip the motor around and it will bolt up. My question is does it matter how the motor is bolted up to the subplate for the solenoid valve to work right. I would have figured the subplate would bolt up to the solenoid valve either way. In the video the A port was mounted at the top and there痴 some writing on the motor G1/2 was at the top.
Just looked at solenoid and subplate again and noticed something there's a small hole in both parts and if you line them up it bolts up but not the way I wanted it.

Have not installed one of these, but I'll bet they can only go together one way. Maybe you marked the ports wrong with the marker

I have the same solenoid and sub plate. Mine has a roll pin in the valve block that aligns with the hole you have your punch pointed to. I have not bolted mine together much less mounted it yet. I hope to do that next week when my fittings come in. I bought a third funtion kit online to rig up for my grapple.

It only goes together one way.

There was no dowel pin in either part I’ll look in the plastic bags tomorrow.

The D03 subplate port holes are not symmetric relative to the hold down bolt holes. It only is supposed to go together 1 way. You should have a dowel pin in the valve body. Perhaps it fell out. Regardless, align the two dowel holes when assembling.
