C6 Vacuum Module Color Codes

I posted this question on the "80 - '86 F-100 forum but no one seemed to have a definitive answer. I also searched the archive posts prior to this one.

There are TWO vacuum modules shown for the '80 C6.

When I went for a new module I was asked which color I wanted.
One code shows "BLACK, BROWN or PURPLE". The other shows "GREEN or BLACK".

I have a Haynes Manual and there is no reference to the module color codes.

The question is What is the difference (IF there IS a difference) in modules and how do I know which color code I need? My old one has NO color visible on it to refer to.

D7OZ-7A377-A .. Vacuum Modulator Valve~Green Stripe (Motorcraft TM-43)

D8AZ-7A377-A .. Vacuum Modulator Valve~No Stripe Specified~Altitude Compensating Diaphram (Motorcraft TM-49)

These are the only two listed for an 1980/87 E150, U150 or a F100/150 with a C6. There are Black and Purple ones listed for E250/350's and F250/350's.

No brown striped modules listed for a C6..

Thanks NumberDummy. I am guessing the TM-43 module would be for me as I live at sea level.

I appreciate the explanation. Ken
