I am going to swap a 93 VTEC motor and 5 speeds tranny w/obd1 ecu into 96 prelude that has a h23a1.
My questions are:
Is the 96 prelude obd2 even with the h23a1 in it?
Will i need a special harness to run the obd1 ecu in the 96 prelude?

At the same time i will be swapping the h23a1 from the 96 prelude into the 93 prelude, so will i need a harness for that swap?
Thanks.
