This style can be routed more like the OEM k-series engine harness through the center or more to the right on the firewall than it's Version 1 counterpart. This routing method is ideal for our (RHD) Right Hand Drive customers however NOT exclusive to RHD chassis and does work fine on a LHD chassis.
Version 2 is also routed in a way which allows you to get around aggressive exhuast manifolds.
