Hey guys I just got a new harness for my civic fog light but it came with no relay. Anybody know where I can get one to purchase?

Its a 4 pin that connects to the switch harness.

 

Not sure what year you have but on my eg my fog light setup just had the switch and plug that went into the fuse box that is controlled by the light switch. What year is your civic. And is it a oem fog light harness or aftermarket.

 

Junkyard would work for a relay just get a fan relay I don't have specific amperage ratings for fog lights but I seriously doubt they will arc more than the inductive load of a fan
