    Wiring Harness, Painless Performance, 64-88 GM, 21-Circuit

    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.


    • NOTE1: Part# L240316 and L240317 minor bulkhead modifications may be required. NOTE2: These high-performance items are not eligible for any further discounts or promotional pricing.
    WARNING: This product can expose you to chemicals including lead, sulfur, nickel, chromium, vanadium, titanium, polyvinyl chloride, and 4,4’-methylenebis (2-chloroaniline), which are known to the State of California to cause cancer and birth defects or other reproductive harm.
