96 I30 P0600 & P0500 ?

[g35wannabe]

the p0500 is to check the vss and its good but the problem is the p0600 is a comms error between the ecm and tcm. it says to check resistance between the ecm wires 65,66,73,74 & 77 to tcm wires 47, 38, 10, 11 & 12. well i have all the wires on the tcm side but ecm wires 73 & 74 are missing??? it doesn't appear as theres been any tampering so i tried to see if maybe they were moved in the ecm plug? nope? its not been moved so where is it? my speedo works fine and trany shifts perfect. i just have a abs & check engine lights??? maryland state inspection won't pass with abs light. check engine light doesn't mater. any help would be great! thanks
