 How To Make The Wire Harness

A wire harness is a systematic and integrated arrangement of cables within an insulated material. The purpose of the assembly is to transmit signal or electrical power. If the vehicle does need to be rewired, it can run from $1,200 to $1,500 depending on the vehicle, the amount of wiring and the time to do it. Older cars, especially those with less complex wiring, are easier to get to and cheaper to wire.

IWISS is here to help people to do the rewiring. Our technical department reviewed the customer feedback and released various crimpers in the past years. Featured with high-precision jaw sets, premium steel body, and ergonomic handles, the IWISS crimper offers more efficient ways to do the wiring using less money in the less time
