I just finish the JDM B16 sirII swap into my EG SI hatch. How do I connect the two Vtec wiring?? Do I need to ground the vtec oil pressure switch if I am using my stock wire harness and p28 ECU??

 

if you're using your stock harness and it's from a civic si, then the vtec wires should already be there.

 

It should be plug and play,all you need to do is run the knock sensor if using a b16a ecu,your using a p28 it doesn't have a knock sensor

 

you shouldn't have to wire up anything. it's all already there. no need for a knock sensor wire, because a P28 doesn't look for it .

 

I mean...I got the vtec signal plug in but the vtec oil pressure switch..I dont know if I should gound it or connect it to the wire harness/ecu.

up.......anyone
I cant hear vtec switch over with the vtec oil pressure wire plug into the harness!!
Do I ground the vtec oil pressure switch or what??

 

look you have to ground the vtec oil pressure switchs one goes to the ecu and the other is grounded the vtec solienoid oh yeah if your using a p28 on a b16 or any dual your ecu will probaly burn maybe your motor might **** up the ecu burned on myne so good luck!

 

if you're using your stock harness, on lead of the oil press switch should already be grounded. the other lead goes to the ecu. that's how it is from the factory.
