I have a 99 S10, When I try to connect Trailer lights to the wiring harness and connect a trailer it will blow the turn signal fuses. The fuses are under the hood. I heard that thier is a connector under the hood to connect the harness is this true.

I've never heard of any connector under the hood for hooking up trailer wiring.

It's not clear as to what kind of wiring on the truck ... is it hard wired into the truck harness or is it an adapter type that simply plugs into the trucks wire harness ? Is it a four pin flat plug ?

Likely there is a short in the trailer's wiring since you only blow fuses when the trailer is hooked up.

Check all wires for bare copper or places where a wire could be pinched and touching metal on the trailer or your tow vehicle's chassis/frame. Remove the bulbs from the trailer's lights and with a multimeter check to make sure there isn't continuity to ground ( the trailer's frame ) on the green , yellow , brown wires. If that is ok, then calculate the amp load your trailer is pulling. Most vehicles are equipped to handle only standard lighting on trailers; one turn/brake signal on each side and one marker light on each front corner. Check your vehicle owner�s manual for specific power ratings. If it is not a short, a pinched wire, and your vehicle is rated to supply the necessary number of amps (power), then consult a professional.

The basic 4 pin wire colors on the trailer are :
- right stop/turn ( green )
- left stop/turn ( yellow )
- tail,license,clearance marker ( brown )
- ground ( white )
