I bought a efan harness from Nelson Performance over 10yrs ago. Took a chance on calling them up to see if they could help me since I had a issue with the fans not coming on high. Did not expect much since its been so long with the harness, but spoke to Ray over the phone and he exceed my expectations. He walked me threw the trouble shooting step by step over the course of 2 days till we solved the problem and was always available when I called. Top notch customer service!!
