Hello all,
I have an 03 screw fx4 4x4 with the 5.4L engine. It currently has the regular mirrors on it and I want to change them out to tow mirrors as I occasionally haul a trailer and have a hard time seeing past it in the mirrors now on the truck. The mirrors currently are electric only, no defrost, no directional/puddle light. I pulled the interior trim panel off to check the type of connector and also to see how many wires the connectors have, as I have heard that some have only three and some have six wires. What I have is three wires on the mirror side and six wires on the harness side. Does this indicate that I could easily switch over to tow mirrors that are heated, even though I do not have a defrost button.

Any info will greatly help. Heated mirrors are not a major concern, but it would be nice to have in the fall and winter.
Thanks in advance.

 

For your truck, I couldnt really say. However, since I have an 01SCrew I would have to wire specifically for the heat and tap into the interior door light for the puddle. I decided not to wire the heat the tow mirrors I got has as I live in Texas and it doesn't really get that bad here.

Depending on the mirrors you get, you may have to do some cutting and splicing, but since you aren't running with a SCrew you're probably fine finding tow mirrors that fit without any worries. If I get home before someone else responds I'll check it to see my Hanes manual has a wiring diagram on the mirrors for your truck.
