    I'm not sure what wires go where, but I do know that alot of them will probably not be used. The only thing electrical going in/out of the transmission case is the reverse light circuit and the torque converter lockup control.

    You will need only 2 wires to make the 700 work. B+ voltage from the brake switch and the ground signal from the computer. Your problem will be when the computer sees it has no EPC control it will disable lock up and try to put your transmission in failsafe, which of course it can not do. So you will have no lockup and if you drive it this way you will fry the converter in short order.
    To make this 700 work you will need to install a lockup kit.
    Summit sells Painless Lockup Kits as well as TCI. Several other companies make these kits. The bottom line is your 4L60E computer will not make your truck lock up without some help from an aftermarket kit. HTH
