i have a dx civic and i got a si wire harness, but the plug next to the brain box doent fit the engine pluge. how do i rewire that??? the si have 8 wire ad the dx has 12 how do i do the wires?

 

dont do it its a pain in the ***

get another dx engine harness

and do the MPFI conversion

 

I can send you a dx harness rewired (if you need)... Pm me

 

THis guy still has wiring inside the car to do because the DX has wiring for only 2 Injectors and not 4, that was harder than creating a whole new engine harness like I did. It does take more than just the underhood harness to make it work.
