    Bring your electrical system up-to-date with one of these new harnesses from Painless Performance Wiring. Aftermarket accessories can put heavy loads on factory wiring and possibly cause harm. These new harnesses use the highest quality thermal crossed-linked (TXL) polyethylene wire rated up to 275°—that's twice the load of standard wire!.
