So I have a 1988 CA mass air GT. I picked up a 70mm mass air meter from the junkyard. I found the correct sensor on many cars.
F2VF-12B579-A2A

Well long story short the 94 and 95 mustangs have a round plug for the mass air meter and the mass air on my car is a square plug. The number of connectors in the plug is not even the same. I looked at some later foxbody plugs and they are round has well.

So was the 88 CA car just a different plug? Wonder if it's possibly to just spice it in.

I was just wanting to mess around with it some.

I took the sensor back and they let me keep the 70mm Housing. I thought about trying my sensor in it but everything I have read says that's not a good idea.

All of the 4-wire MAF plugs are the same. 88-93 connectors should be the same. Do you have a pic of yours? Should look like this

You can't swap your electronics to the 70mm housing, you will need the 70MM electronics which are compatible with your ECU. The plug should have plugged into it as well
 
Mine looks like that. Totally different plug. Looks like the CA mass air 88 is different.

You shouldn't have a 5-wire MAF. 88 through 1995 were 4 wire MAF's. Can you take a photo of your current MAF electronics so that we can see the part numbers on it? The 5-wire MAF's started on the Mustang in 1996, although I see an E4 part number on that harness plug which is a 1984 engineering number.

EDIT: as I look closer I see it is a 4-wire MAF in a 5-wire plug. Strange, but you can probably cut and solder the more common style connector on and hook up to the SN95 70mm maf. I wouldn't do that just yet and would confirm that the plug on the '88 MAF is unique. I've never personally heard of this before, but there are only a small number of CA MAF cars so not hard to imagine it's not info that comes up a lot.

Would be interested to see the MAF part number and compare to the 1989+ MAF numbers
 
After some searching, yes, 1988 CA cars with MAF have a unique harness and sensor

Sensor part number should be E8ZF-12B579-AA


Your options are make or locate an adapter harness, or cut and solder on the round style plug adapter
 
Yea kinda exciting huh? Lol yea it's 4 wire in a 5 wire plug for sure. Threw me for a loop for sure because all the research I did said that sensor would work from the 94

It's a D I think instead of a 0 on the sensor. Yea I had that thought has well maybe the plug was spliced. It does not look to be. I know I'm the 4rth owner. With the other 3 being relatives of each other. Original owner was an old guy sold it to his nephew. He then sold it to his brother who parked it in a garage for 10 years lol.

Then sells it to me for $1500 because he could not smog it. Of course I just found a stock h pipe and smogged it.
 
Did that same maf sensor come on a escort to? My thought is the 88 CA car must have been assembled on a different line or different place. Since it has some different parts. My fuel pump houseing is different then other mustangs also.
 
Ok i know this post is old but i have a similar question. I recently purchased an 88 maf Notchback and the wiring for MaF looks fishy. Computer number is 8LF. Car starts and idle with maf unplugged but runs like :poo: plugged up

8LF is the right ecu for a mass air '88

That MAF wiring is a little odd, and it's been reloomed so a previous owner did something there. Hard to see from your pics what's going on. Can you take one set back a little bit

Not trying to question your intelligence but you say it ls the correct computer for Mass air based on the list i posted or past experiences because heres another list that classifies 8LF as speed density. The previous owner got car the same way so owner before him did something for sure. The red wire is splice to this pink/blue wire then ran to the ac relay thing.
