since im planning to buy only the longblock,, which wiring harness should i use for the ls vtec to work corectly.... can i use a 95 civic ex harness? because i have one in hand. i was thinking of using that harness and a pr3 or pwo ecu...give me some advice..please

 

what exactly do i cut and splice?,,,(i hate that idea) waht do i use to wire up the vtec solenoid?

 

what CAR is this going in?

u said pr-3 and pwo that would make me think 88-91 rex/hatch

if it is a si then your all good. just wire vtec and go

if its a dx/hf u have to convert the harness to SI injection, then add vtec


one is multi port one is dual port, i cant remember which is which

 

DX/HF is dual port fuel injection and SI is multi port.

 

hf is multi port and si
dx is only duel port
