That's really interesting. I was going to have 2 front 2 rear switches but ray said I wouldn't need to. And I wanted them for exactly the reason you said - to get them all equal. As the cub may be not exactly equal in each corner, I was going to see what it's like and then may be have ray knock up some collars/spacers to sit on the ram.Hi mate,
I had the very first 4 valve classic mini kit from rayvern and worked with them to iron out the issues.
The first kits were two valve but gave Issues with levelling etc
I’ve noticed that you’ve got just two switches “front” and “back”. In all honesty you’d be better off having two fronts and two backs.. you can fit a switch link to control both rams at the same time if you wish but you’d still have the individual control for bleeding the system and levelling control issues etc.
Rayvern states these are self bleeding but I found that the only way to fully bleed these was to pre fill the ram and pipe off the car and then fit it to the car and pump.

I’ve got the original wiring diagram somewhere if it’s helps (doesn’t look like you’ll need that though)
Regarding filling up the pistons before installation, pity you did say earlier as I've put them in today. I might have to pick your brains on the wiring to the compressor if I may.
Unfortunately the witing diagram ray sent over was a very pale picture taken on his phone.
