Do Pre-1996 JDM B18C motors already have the VTEC pressure switch?
as topic says, i was looking at the two solenoids on the USDM and JDM motor and couldnt find a difference between them. it looks like it already has one...

What he's referring to is the 96+ JDM motors not having a VTEC pressure switch which is true. They all have a VTEC solenoid but the 96+ JDM motors do not have the pressure switch built in. All pre 96 JDM motors and all USDM motors have the pressure switch.
I'd like to add that there is a simple wiring method that you can do if you are using a pressure-less solenoid with an ECU that looks for the pressure switch sensor. If anyone runs into this problem and needs to know how to wire around it without changing the solenoid, just let me know.
Re: Do Pre-1996 JDM B18C motors already have the VTEC pressure switch?
I have a b18c 97 JDM with no pressure sensor.
I'm using a 96 5spd EX harness.
I have 2 connectors tgat are the same in the same area, around the vtec sol.
one is wired red/wht and grn/blk
the other is blu/blk and blk
I'm also using a JDM p72 ecu
can you tell me which one is used for the switch located next to the coolant temp?
