I'm not familiar with that brand of wiring harness, but double-check your connections, both physically and to make sure that you have the appropriate wire meeting up with the correct wire. If the wiring harness does not have the industry standards color codes on it, I wouldn't use it, simply because it would be so easy for the company to keep up with the industry color codes. The ones you really want to double check good are your red, yellow, and black wires. Speaking of the black wire, you may also want to provide a second ground to a metal part of the chassis to make sure that the ground in the wiring harness is really good.
