I installed my fan switch according to the directions provided in my 93 z28. however when the key is out of the ign. an accessory fuse. the low fan led is lit. in the off position. when i flip it one way it remains lit , when i flip it the other it lights up both, but the fans do not turn on. when i turn the key to the on position the led goes out and when i flip the switch either way i have no leds lighting up . i read on a previous post that the blue & green wires need to be switched on obd switches. any help would be great thanks

 

anyone else install this switch?
