integra ls to gsr

[b303monster]

freind is doing a gsr swap into his his 2000 integra ls wanted to make sure i got all my stuff right on the harness is their anything that would need to be changed on a ls harness for it to run right on a p72 ecu

Just add vtec, and as long as the gsr is from the same year everything should plug in..

He'll need to wire up a knock sensor as well I believe.
As far as adding vtec .. there's a pressure switch and the solenoid.. both need to be wired up

Isn't there a knock sensor on a 2000 LS

update so went and made sure everything is correct and the only thing is we were going to put a p73 on it and noticed plugs were different then the ecu. the harness is obd2b harness and the ecu is obd2a. Witch ecu works on it?

You need a obd2b ecu or you can see if someone makes a adapter to make it obd2a..
