Bring your electrical system up-to-date with one of these new harnesses from Painless 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 degrees—that's twice the load of standard wire! Depending on application and accessories, choose between 12-circuit or 18-circuit versions.

Part# S220102 includes pre-terminated plugs for the ignition and turn signal switches.

Notes

  • Part# L240316 and L240317 may require minor bulkhead modifications.
  • This item is not eligible for any further discounts or promotional pricing.
