Installing wiring harness for high wattage headlights

[jimbo231]

I bought some high wattage nokya stage 2 9007's and heavy gauge harnesses for my 2001 sport and I can't install the harness. It's suppose to just plug in but my wires for the headlight come from a taped up spliced set of wires. How am I suppose to install it?

Unwrap the splice, determine which wires do what, hot, ground. Insert wires into plug on your harness. When everything works as it should, cut the plug off the harness, splice the wires.
If you don' t want to go that route, go to LMC or PAINLESS and get a harness to operate your headlamps through a relay. It operates off your head light harness at the headlamps.

Is the 2001 sport suppose to have a factory connector where I could just unplug the stock harness to upgrade or are they spliced from the factory?

I have no idea about your 01. I have used the harness from LMC Truck on an 86 F-150, and it just plugged into the headlamp socket, used relays from the battery.

If I use the high wattage bulbs without the heavy duty harness what is the worst that will happen?

burn baby burn... :-( depending on what and where things get hot and melt. Actually you are probably over looking a comment by a previous poster... about a "relay". You will likely need a relay to direct power to your lights otherwise you are asking for "fun" in a few areas in your interior... like your light switch and MFS.

Do you have directions with the harness? Is the harness for your type bulbs?
Usually a harness is plug & play,

Here is the harness do I just add it to my existing wiring....plug one end in where the old plug plugged into the light and the other end into the new bulb?

What you have a picture of is not going to be of much help. What you want is a harness that uses your existing wiring to excite two relays ( high and low beam) which are wired directly off your battery. If you go to LMC Truck, you will find the harness I was telling you about previously. If you use what you have there, you are still pulling all the amperage through you factory wiring and head light switch, which is asking for trouble.

Yes thats exactly how they work. The harness you linked to isnt any different than the $15 sets with ceramic plugs on ebay. Only purpose is to keep the stock plastic connector/wires from being melted by the bulb heat at the socket. Thats a bare minimum required product when using 80/100W or higher bulbs, but doesnt protect the rest of the wiring and switches from an overload.
