home depot wire fine for use in car door?

I don't know if this has been asked before and if it has I am sorry. I am looking to make a wiring harness for a alarm, Long story. I went to Home Depot and got some MTW/THHN/THWN wire to use. Now I am a bit scared because I think I may have bought the wrong wire for the application. I am worried about the wire failing because of it has to flex with the door opening and closing. Is this wire suited for that task? Its 14 AWG wire and seems very good but I want some reassurance. Thanks you for looking!!!

If this is just for contacts, and not carrying any current, then any small guage wire will do.

Wire that has many smaller strands works better for flexible applications than a single conductor wire does.

Doorbell wire will work.

How many conductors do you need for each door? What exactly is the harness for? (short story)

I know just enough to be dangerous. VERY dangerous.

I am looking to make a wiring harness for a OEM 1992-1997 J30 keyless entry control unit made by Alpine to use for 1992-1993 Infiniti Q45's. I am using stranded wire as well. The most this wire will see is 10 AMP, thats the the fuse is rated at. And the 14 AWG wire can handle 15 AMP rights? But like I said the only moment the wire will see is the door opening and closing. Other than that the rest will be under the carpet and routed OEM like. Do you think the wire from Home Depot is inefficient for such a task? I want this wire to last some time thats why. I also have to run two wires in the drivers side door, One for a unlock sensor and the other for the door lock actuator.

You say you are using stranded wire as well.  is the Home Depot wire stranded? 

All the wire in the harness is stranded.

From the description and functionality I think it should work just fine.

You can compare the wire that is already used for this purpose in the OEM harness and if it is equally similar it should work.

Are you following a schematic? Do you need diodes?

If it isn't stranded wire, don't use it period. It will break, otherwise stranded 14 gauge is fine. Did I spell break correctly?

Thanks all for the help!!! Just to be sure, Best Buy and other car stereo/alarm installers use this wire on the door right?

Son, if it's good enough for all auto manufacturers . . . it's good enough for Best Buy!

Now just git r done.
