Re:Manual Overdrive engagement

Calvic,<br>I simply spliced a wire into the orange with green tracer wire coming out of the transmission, then ran the wire up into the cab along the parking brake cable and mounted (taped) a switch to my steering column. The other wire from the switch is spliced into the ground for the trailer controller (it was right there anyways) and away she went. Literally! ;D<br>Hope this helps.

this is the post i read. i know all the possibilities. what is a momentary switch?

to teh top? any mroe insight on this?

 

The switch, when pressed provides a momentary ground pulse that activates/de-activates the OD. It is not a "constant on/off" type switch.
Hope that helps.

pb..

 

but its not like i have to push and hold it in right, its like the switch on the dash currently? push once to activate and once again to de activate when no longer using.... and am i correct on the wireing of this? orange/wht splice to switch then to a ground scource?

thanks all, jiMMy

 

I had this problem for quite some time, I used contact cleaner on the TPS
connector plug haven't had any problems since.

Hey, I delt with the god foresaken TPS 4 days after I got my truck. Look at this thread about mine. https://www.dieseltruckresource.com/...threadid=47876

I'm not good at doing the fancy link thing yet. I'll catch on eventually. Hope this helps....

 

A momnentary swt you have to push and hold to stay activated. This is not what you want. You just want a regualar on/off swt.

For mine I used a floor mounred headlight dimmer swt. Its mounted on the left side up by the e-brake cable where its out of the way. I just tap it with my left foot and viola, OD. Don't have to avert my eyes or take my hands off of the wheel. Handy when you are racing.

I would reccommend installing an indicator light as well to remind to to turn it off when coming to a stop. I also hit the OD lockout swt when using it so I don't get confused by teh computer upshifting to OD.

 

well i drover again today. it didnt do it at all on teh way to work, (20miles) on teh way home it did it once. it always comes right back though.

so this weekend im gonna take her off and clean all connection points and hope ti doesnt do it for my turkey day drip.
i supose i can run all wires for the switch idea and hook them to teh switch if needed so im not stuck flooring it to do 60 there or back.

thanks all, jiMMy
