hey i got 91 honda civic si and i just bought a d16z6 motor i was wondering if i should use the original wire harness from my A6 or use the one on the Z6?

 

what is it, obdo- 1-2?

 

use original harness & steal plugs from the z6 harness as needed

 

stick wit ur stock si harness the only plug u have to modify is the cooling fan switch cuz ur original one is located on the back of the block and on the z6 its on the thermostat housing. u can find that plug at any junkyard and then u just have to splice that plug to ur old wires and ur set to go.
