I performed the same conversion, and also have the "headlight leveling" issue. Did you find a resoultion?

Ok I was able to get the wiring diagrams and ECU pin diagrams.

The first image is a scanned copy of the directions that came with the kit. As the directions state i am to cut the "violet with red stripe" wire going into the ECU. Looking at their electrical diagram that would mean i am to cut Plug C PIN 7.

What Strut Masters fails to tell you is that there are three plugs going into the ECU

A12(A) A13(B) A14©with several violet with red strips wires.

Finally you will see that they not only didn't give ECU pin diagrams but they directed me to cut the WRONG WIRE

Here is a scanned image of the CORRECT Air Suspension ECU Wiring diagram

Which correctly directs me to cut the wire Plug A Pin 7 and NOT Plug C Pin 7

I cut the correct wire (which i got from AllData.com which is the site for Toyota specific technical information) and the HI/Reg light went away.

I like the ride of the Strut Masters but their directions are lacking enough information to do the job right.

If anybody has any technical questions about doing the switch your self just ask away. You do not have to do a few of the steps they want you to (like take out the rear drive shaft)

I still have the headlight leveling problem fault. I know the system is hooked up to the suspension just now sure how i can either bypass the system or get it to work as is.
