88 vert turbo swap
 

Almost done with my s4 turbo swap have a few questions. I have a wire under th engine on the driver side harness it is yellow and red can't figure out were it goes also I rewired my temp wire like everyone said and it goes half way up then jumps up to h when driving also the black ground wire mounted on the trans housing I can't find a mate for it. Any help would be great. Also just found a leak in my front cooler line if anyone has one that would be helpful.
