I know the solenoid gets hooked into a 12V and the ECU A11, but is that the A11 on the ECU or the wiring harness...and also, how do I attach the wire to it?

 

do I splice the A11 wire?

 

A11 at the obd1 ecu pinout.

 

Does the wire from the conversion harness get removed then? Because there is a wire running from the conversion harness (obd2a) that runs into that pin

No, the wire & pin stays in the obd1 side of the obd1 plug. You are running a11 directly to the solenoid.

 

Yea, someone on turbod16 told me to splice the wire on the harness going in to the A11 pin with the boost control solenoid wire. Thanks

 

One other thing. My wastegate is internal and I was looking at the solenoid wire up diagram and since I dont have 2 p orts for the wastegate, then I'm not entirely sure how to wire up the solenoid lines.

 

Wires go the same way...its the vacuum/boost lines that change.

Port #2 should be connected to the intake manifold/boost source and #3 should be connected to the internal gate.

#1 is left open to atmosphere

...if I remember that correctly off the top of my head.

0% duty is min boost
100% duty is max boost

 

Question... I just hooked up the Hondata boost solenoid in my car yesterday. Running a Tial external wastegate I've got the top side hooked to COM and the boost/vacuum source hooked to NC of the solenoid, leaving the normally open to vent. (Wanted it hooked this way just in case of a failure I'd still be running off the WG spring) And the bottom side hooked to the boost/vacuum source like normal. Yet now when I start the car, there is a decently strong vacuum coming from my NO side of the valve. Is this commonly what happens and that's why they put the muffler there usually? Or I was thinking maybe I'm leaking air through my diaphragm in the WG. Wanted to get a second opinion before I went tearing into the wastegate. Thanks
