I was looking at a pair I saw on ebay and they look a little different than the S5's 550's. Mainly the plugs on them. How hard is it to convert the plug style on and injector or rather on the harness?

EDIT just so you all know I tried to search about three times and it always gave me a 502 Proxy Error so I said **** it and posted about it.

get a set of plugs that will plug into the injectors, cut off your plugs, solider on the new ones.

I belive they are the same plug found on the 86-87.5 cars. the brown(ish) top low impeed injectors.

That rectangular plug is a Bosch type of plug.  Some of the big auto parts chains (i.e. Kragen/Schucks/Checkers) carry plugs with bare pig tails.

Ah also another question I have is what happens if I have primaries that are low impedance and secondaries that are high impedance? vice versa? how do I make it work?

Depends - if you're trying to use low impedence fuel injectors in a car that originally used high impedence fuel injectors, you'll need to wire in some high current 10-ohm resistors.  These things are also known as "sand block" resistors, cause they are blocks of ceramic.  Get at least 10watt rates ones - or better yet, 20watt ones.
