Vtec Wiring! Quick Question!

I just need to wire from the ECU to the GSR engine harnesses, right?

These 4 wires are found on the GSR engine harnesses at the shock tower, right?

A4 vtec Solenoid
A17 Secondary Intake Solenoid
D3 Knock Sensor
D6 vtec Oil Pressure Switch

Car: 93 Cx
Motor: 98 GSR (USDM)
 
Ok, I noticed on the GSR harness where it meets the Cx harness that the vtec solenoid wire (A4) is there :thumbup: Also the vtec pressure switch is there (D6) on the harness just below and to the left of the solenoid :thumbup:

How do I find these 2 on the harness where the GSR meets the Cx:
--Knock Sensor (D3) is there?
--IAB Solenoid (A17) is there?

Also, on a vtec diagram I have there is an A20 - EVAP Purge Solenoid. Do I have to wire this as well?

I wired the 4 that I mentioned in the original post to the ECU harness at the kick panel as you can see in the pics :thumbup:

Am I done at the ECU pin outs now?

Thanks for any help!

is it OBD1?

Motor is 98 (OBD2)
ECU is P72 (OBD1)
Car (OBD1)

This is basicaly all I need:

How do I find these 2 on the harness where the GSR meets the Cx:
--Knock Sensor (D3) is there?
--IAB Solenoid (A17) is there?

All I have to do is find the above wires on the GSR engine harnesses and solder the wires I ran from the ECU to them :)
 
i would just cut the connector off at the VTEC solenoid and leave some extra length on the wires, then run those from the ECU directly to the solenoid.

I want to do everything as neat as possible. I even have the male / female pins that go in the harnesses.

I just went outside to check the A20 pin at the ECU. It's there

I also took another look at the harnesses on the passengers side.

There are only 3 wire openings on the 3 CX harnesses

They are shown here:

1 & 2 both match up for both pics!

#1 -- VTEC Solenoid
#2 -- VTEC Pressure Switch
#3 -- knock sensor

Where is the IAB solenoid? Either on the motor or at the harnesses? I don't think it's on the harnesses since there are only 3 openings......
