Ive recently bought a '98 S-10 Blazer to tow our daughters karting trailer to & from the races....Ive installed a hitch & also wired the trailer lights into the supplied lights thats behind the left plate lamp. It was a 4pin plug with of course 4 wires...Ive got them all wired correctly but the only issue Im having is I dont have turn signals. The breaks & light work..just no turn signals...obviously Im missing something...can someone please help. Thanks in advance ...Skeet.

 

Solved it myself...it was the supplied terminals that came with lights....do not use the small blue terminals that you place the wire inside & close down on it...they arent worth 2 cents....nothing but junk....I just hard wired it.
