Trailer RELAY's
 

My trailer lights wont go on? I noticed both relay's slots under the hood marked "trailer" are without any relay's.

Anyone know if these relays are required even if the trailer package was/is an after market one?

Even the dealer could not advise accordingly? Maybe somone, in there down time, can run out and take a look under their panel?

TIA, Paul

if you have the factory set up they should have the relays. if it is an aftermarket set up then the wiring harness just plugs into the factory tail light wires. check under bed and follow tail light harness. there should be a connector for this. my 97 was this way and all i did was buy the aftermarket harness and plugged it in.
