ok all i have to do to finish my swap is do the wiring for vtec, ive read that there is no need for a oil pressure switch if you have a jdm ecu so i need it ansered as soon as possble and please only anwser if your 100% sure, thanks in advance!!!

 

I did such a swap (JDM VTEC into SI chassis) and all 3 wires were needed.

I used all my wires in my swap.

yep JDM ECU. 1 wire for pressure switch and 2 for vtec solenoid.

2 to the ecu ( a4 & d6) and 1 to a grounding point.

also you will need pins to connect to the ecu. (check my sig)

 

Have you checked to see if your car is pre-wired for VTEC? It is easy to see, look for these wires in the pic:



If you have the connector for the solenoid in the pic then you can find the light blue wire for the pressure switch in the big plug circled. The other side of the switch is simply grounded.

But to answer your question, yes, the JDM P13 ECU DOES look for the VTEC oil pressure switch so you must add the wires.

 

yeah it prewired i probuly should of stated that! i already did the yellow and green wire to the solenoid but where does the light blue wire extend to, a picture would be apriciated thanks!!

 

Look at the pic. The connector on the top of the top has the light blue wire in it. You will see the wiring comming in the firewall side but nothing comming out the other side. Just run that wire to one of the wires on the VTEC oil pressure switch, then run the other wire on the switch to a good ground. Polarity doesn't really matter as it is just a switch that closes when it gets enough pressure.

HTH,

 

Oh, I think I get it. You want to know where the VTEC oil pressure sensor is, correct. You can see it in this pic:



It is the one on the right in that pic

well, depending on where you got your swap from you should have at least received a cut h22 harness that was on the engine. If you received that then you just take the connectors off that harness and splice them into yours

 

ok ill look for them i might off takenthem off does honda sell them or can i use any connector from any vtec car?

 

I'd guess any VTEC one would work, but dont quote me on that. I asked the guy on the phone if that plug was there and he said yes...guess he misunderstood me.

 

alright guys thanks i understad now thanks for all your help!!
