Hey guys...i'm going to do drop ls/vtec soon in my car ...obd-2 bottom block and a obd-1 b16 head... I was wondering if I need a different engine harness or if I can just use my LS engine harness... if i do need a different engine harness... which one do i need? any help would be SWEET!...THANK IN ADVANCE!!!

 

u can use a obd 2 DOHC VTEC wire engine harness and get a obd 2 to obd 1 harness to then make the motor run on a obd 1 ECU

 

I believe you can just use your harness and add the vtec wires along with the knock sensor.. that should work..
