i just installed the Schroth Harnesses yesterday.
the Schroth Rallye-4
Relatively easy install...took about 2hrs.
but with these belts you cannot use them with rear passengers. If you have people in the back you have to use the stock belts.
I don't know of any harness off hand that will allow rear passengers.
I take some pics today after work and post them either tonight or tomorrow.
