Hi, someone i know just got some levinson pups from a levinson blade. 2 single coil size ones that have a silver white and red wire. can you give me a clue how they should be wired?

Silver will be shield, most-likely, with white being 'ground' and 'hot' respectively.
For completeness:
Reversing the white and red wires will invert the phase but will not change polarity (polarity is the magnetic orientation of the magnets. You'd have to flip the magnets to change that).

I thought that too. Thing is he has both neck and middle with red and white. They usually change colours for middle? So white is ground in both cases... white to silver... and flip the wires on the middle pup if needed?

The wire colours should mean the same thing regardless of position if they're from the same manufacturer and are part of a set.
If they're a mix-n-mach bunch, all bets are off.
Check with with the manufacturer to see if the middle is reverse-wound, reverse polarity (RWRP). Chances are a middle is RWRP but you only have 2, so you don't have a middle. If these are both humbucking pickups, there is nothing else to do since they're factory-wired to either series (likely) or parallel. If they are single coils and it hums a lot with both selected, flip the red and white wires on one pickup. That will reverse it's phase and should help to lower noise.
Look up the grounding schemes in this forum to get sufficient shielding sorted out and you'll have a pretty quiet axe.
Don't just connect the shield to the ground on the pickup.
The shield should be grounded but the white, 'ground' should be treated like a signal wire. There should be a path of proper wire between that white one and the output jack's 'ground' connection.

Don't get the grounding part? I always just connected both wires to ground. What's that about?

This led me to believe you were going to connect these together and be done with it. Both to ground is fine, so long as you don't use shielding to carry your signal. If you attach the white and silver to the back of the volume pot, say, then use a wire from the volume pot to ground the tone (and however many more pots you have) then connect that to the ground on the jack, you're fine. If you ground the two wires to the pot but then reply on the pot's connection to the shielding, connecting the ground on the jack to the shielding, you're not in such a good place.
