99 civic dx swap

[jspeceg]

ok here it is. i have a 99 civic dx. i bought a semi built y8 motor for a really good price. here is the problem: do i modify the existing dx harness and run wires for the knock sensor and vtec and modify for iacv, or do i just get a y8 harness? now, the only draw back i can tell with a y8 harness, is that there is no secondary o2 wiring on it, because it runs through the car and through the floor board on the ex and si's. how do i compensate for that?

well first thing you should really use your stock harness, just add the vtec wires to harness

use the article there for that, second there is no knock sensor for a single over head cam engine if i am not mistaking. i am almost pretty dam sure there isn't
third you are going to need this for your IAVC

it will show you right on the website how to do the wiring
for your o2 sensor just cut one wire at a time and extend it so you can reach your cat or go thur your car remove the rug and go from there fairly easy to do just do your self a favor and cut one o2 wire at a time so you don't confuse the wires i hope this helps you
