make sure your lo-hi and hi-lo arent the same

incorrect
example your lo-hi would be 4200 and your hi-lo would be 4200

correct
example your lo-hi would be 4200 and your hi-lo would be 3800


not saying those settings are right for the car just merely giving examples

also make sure the harness is connected properly, it can really fuck with you if it isnt.

ill double check the wiring again but im pretty sure its right. and the settings were different values so who knows why it wont work... thanks
