With Painless, you're simply investing in the best!

Painless wiring is simply the highest quality wire you can buy! All Painless harnesses use thermal cross-linked (TXL) high-temperature wire. TXL wire has twice the voltage rating of standard general purpose (GTP) wire and can withstand temperatures up to 275 degrees. It delivers performance on demand in high-performance applications, plus, it will not kink making it much easier to route. Painless also utilizes OEM-style fuse blocks that feature easy-to-find modern blade fuses, clearly labeled circuits and corrosion-resistant construction. With Painless wiring, each wire is preprinted with the application so you know right where it goes. All kits come with more than enough wire and terminals to do the job. You cut and route to suit your needs.
