A-Trac switch harness advise for TRD Sport

So, I’m gathering bits and pieces before attempting the “yellow wire” mod or more recentl/better the “yellow with black tracer” mod to allow the TRAC to function in 4-lo.

All I need is the 4pin connector for the back of the OEM switch and I’m having trouble finding one.

Even a buddy at the dealership couldn’t dig one out of the wiring harness bin.
Wrecker was a bust also.

I’m hoping someone know a part number or has found an aftermarket clip that works.

I’m open to other suggestions.

Here is the switch in question.

 

My OR has factory A-Trac but due to that, I have an electronic brake booster that is significantly different than the Sport's manual brake booster. Can you have A-Trac w/out the style brake booster I have?

 

In a word: No

I get Trac in 4lo with this mod. Its like A-Trac but not as good. Call it the poor man's A-Trac.

 

Any link to this?

 

My bad. I thought you were saying A-Trac but you were saying TRAC.

 

Yes, Although it isn't really helping me with the purpose of this thread

Help me out here, what are we looking at?

Is this the connector I need?
I see 8 pins, not 4.
Where could one order one of these?

 

Bump this up as I’m looking for the same thing.

Got to be someone resourceful out there who’s done a factory look yellow-wire mod using an A-Trac button.

 

Sorry to revive this old thread but did you ever figure this out?
