the yellow wire in common with them all, is that power or ground? should the 4 of them alll be attached together and grounded?

 

yellow wires that are the same color are the power source, the computer grounds them.

 

are you 100% sure on this
people?

 

yellow/black= power, injectors are all powered together but the ecu grounds each one.

 

12v or 5v?
what kind of fuze should i run? itll be going right to the battery

 

if you use an obd-0 computer u will need a resistor box and run the left over wire to the battery. if u use an obd-1 computer you can just tie them together and put them to the battery. just make sure to fuse them either way you go. a 10 amp fuse will be fine.

 

if i put them to the battery isnt that bad?
shouldnt i have them on an ignition wire?

i meant 12v switched on with the ignition, sorry.
