Have notice pics of Front upper control arms with the harness located in slots attached with zip ties to the top of the arm and some attached underneath the arm with zip ties in the slots with wire underneath. Does anyone know the factory suggested method of installing these harnesses? Harness on top or underneath the U.C.A. ??

 

Kelly, all I have messed with the wire was on top.

 

The more slack you can provide, the better off you will be in terms of having to deal with ABS issues due to taut harnesses that eventually chafe or break....

 

When I've done ones that hadn't previously been replaced (as they came from the factory), they were on top. I've always put them back the same way.
