New vintage usa highbeam/engine light prblem

[70CHEVYBB]

Just in stalled a NVU performance black gauge kit. two problems 1) hight beam light stays on when lights are turned on, it does get btighter when the high beams are turned on. 2) check engine light stays on all the time. i have checked for codes and all are cleared. this is a 5.3 with psi harness and computer. i also installed a new AAW harness for the truck. the brown engine light wire from the pcm goes to the the black wire on the light and the red wire goes to power. the high beam light black wire goes to ground and the red wire is hooked to the hi beam wire in the AAW harness. i called NVU and have no fix for the high beam light problem and said I need to use a relay on the check engine light . Any thought on this???
