What Wiring harness do I use for a B16A Going into a 93 Integra??
and Could I Use the wiring from a B20B on the b16A ?

 

i dont think theirs any problem with the wiring it will most likely be a chasis specific plug adapter you will need or pin adapters for your alternator dizzy and engine to under dash wiring harness depending on what your running if your using the same setup on the motor pulling it out of one car to another you will probably just need the chasis plug and an obd 2 to obd 1 jumper harness for your ecu .... i think thats correct although i have never owned a b20 but i dont think the wiring is any different other than it being a different adapter for the b20 to b16 setup.
