how do i check codes now that i dont have the obd0 flashing light? is there a wire on the harness that i need to connect so the guage cluster check engine flashes the codes? car runs great but, sometimes the check engine light goes on.

 

Depends, did you use a conversion harness? most of them have you jump or ground a certain wire or jump the service connector thats in the engine bay

 

if its a jk then you join the 2 wires in the directions.... if not, try what Vee said

 

yeah i used the same style harness as rywire... do u know what color wires i need to connect ?
