I know this is a non vtec forum but im sure you guys will have an answer for me. I just got an ls/vtec setup for my DA integra my question is how do i connect the vtec solenoid? I know i need the ls vtec kit and how to do the full swap thnx to project car mag but they dont say anything about the solenoid. So i need the ls vtec kit upgraded ecu chipped with hondata s300 correct? And then what about connecting the solenoid? Thnx for the help

you need to get a harness from boomslang or rywire to convert the car to obd1 and that has the vtec wiring built into it

Car is already obd 1 and i noticed that the connectors been cut just a piece of wire

90-91 DA integra are pre obd and 92-93 DA integra are obd 1. Find the right connectors that will fit the vtec solenoid. You will need ecu pins from a obd 1 car , so you can slip it in the ecu plug. And about 3-4 ft of wires. I also can make a Harness with the connectors and pins. pm for pricing.

ecu pins:

A connector has 26 pins - A4- vtec solenoid.

D connector has 22 pins -D6- vtec oil pressure.
