Hi all, i am working on a friends 98 yukon 350, auto shift 4x4, and i just replaced his torque converter. when i re-installed the tranny and t-case, i cannot seem to get the wiring harness figured out. most of the plugs were easy, but i have a couple 2-wire connections that are bugging me, and i can only seem to find a plug for one of them. i know i have the shaft speed sensors correct, the dealer printed out a schematic for me, but i cannot find the extra plugs on it. with only the one hooked up, the 4-hi light stays on, and it is in 2-hi. when i push the 2-hi switch, it will not shift over. im wondering if i just have the wrong one hooked up, but im not sure that there was an "extra" plug. does anyone have any help for me? anything is greatly appreciated.
