71-73 Map Light

Does anyone know if the map light on 71-73 Mustangs were standard or just optional? And if it's just an option would the under Dash harness still have a dummy plug connector if someone wanted to add it on?

Optional. On every car I've touched had the harness connector there. Easy to add on. 2 screws and plug it in.

Wiring harness was different. Only had the connector if you had the convenience group option. Here is a long thread about it:

Previous owner(s) added it to my car. The factory plug was not there, I had to fix the one they "added."

72-73 cars the dash harness no longer had the map connector built in.

It gets confusing because the 72-73 might of still had the footwell lighting connectors which would of been part of the convenience lighting group, but the map light circuit is gone unless you got the convenience group option.

71 cars usually had the map connector tucked behind the dash, however late 71 car may or may not.

My early 72 does not have the map connector. Long ago I bought a map light to retrofit my car because I was told all the cars had the connector behind the dash. I found out this was not the case at all. I gave my map light away since I did not want to cut up my dash harness and retrofit the connector.

my car didn't have the Map light connection there, its an January 1972 build.

I used a 4 position trailer wire harness connector w the first 3 pins fit right in, and used that to wire up the map light.

If car has no map light connector it's not as simple as just running a power and ground to make them work?

The map light also works with the door switches as a courtesy light

you need ground, constant 12v, and door switched 12v.

check this tread, I have pictures and I wire pin out in it, and pictures

you can wire it in, but its is just more hacking, as imusa76 pointed out. It would of been nice to just plug and play the map light, i just didn't see the benefit of taping into the wiring in 3 more places for a light. had the connector been there i would of just plugged in and added some value otherwise wasn't worth the effort.
