Yep - people have been doing the duty-c mod for years. Well known around here.

That's a good write-up. But am I reading that correctly? he's installing resistors to mimic the resistance of the solenoid so the TCU doesn't know it's not connected?

 

 

Andyjo documented years ago that you can just run the wire through a switch. The only time the TCU verifies functionality of the solenoid is on startup. And if you leave it disconnected at startup, all it does is make the "AT oil temp" light flash.

 

 

 

Much easier method: 1. find wire 2. cut and extend ends to where you want your switch 3. install switch
