PPV Tow/Haul setting?

[PG01]

Don't remember the threads, maybe Pete does. @Galante

It's those two J-Case fuses right in front of the studs. Not all the trucks are wired the same but in my manual they are 63 and 68. There are others like 6, 10 and 25 that power the controller, trailer back-up lights and trailer parking lights.

m6 x 1 and m8 x 1.25 both coarse thread

I wonder if i install the shift lever with the tow button on it and plug it up will the tahoe recognize it.

didn't you say you added the shifter with tow button and it worked? all it takes is a momentary ground to the bcm, you wouldn't really need to have the shifter all you would need is a bump switch connected to the right connector on the bcm, some of the vans have the tow/haul button on the dash instead of the shifter knob

Yea, it lights up, i havent really played with it, but i did hit it while going 50 and i saw the rpms jump a bit.

Do you happen to know which connector and pin that is for the input? I could easily do a pushbutton.

bcm x1 connector (say's it is the light green one) pin #23, see attached photo from gm upfitter guide
that pin would need a momentary ground after the key is in the run position, each time the key is cycled you would need to do a momentary ground just like as if it was on the shift handle.

Perfect, many thanks. Now I have to find the pin P/N again. I know I’ve saved it.

I don't have a button either.

Me too, no button on my 12 PPV... and I tow a 21' travel trailer

Only the six speed transmissions come with the +- button on the shifter, from what I understand this is on 2009+

My PPV has a six speed, but no tow/haul button... looking at converting to one

I'll try this on a button switch rather than change the shifter, thanks

That’s my plan as well.

Yea by reading the little bit of this thread it seems like a lot of functionality with the GEN3 GMT400 is there in the wiring harness (exceptions are heated seats, NAV/BOSE audio, and a few other things) and they are pretty much "plug and play"! I think that the TOW bottom when pushed either locks or unlocks the torque convertor? I like using the buttons when passing people on two lane roads to "set" the tranny where I want it since the TCM is junk in the GMT400s

That’s what I ended up doing in thecopcar. I already have spare dash switches in Lola, so I’ll probably salvage the terminals and pigtails from the old shifter I already removed to reuse for that.
