Any differences in these Fox and SN95 stuff...?

[88 Fox GT]

I need to know if there are any differences, between these Fox bodies and SN95s parts. They are as follows:

- Mass air flow meter
- Throttle position sensor
- Idle air bypass

The reason I ask is because I am changing most of my SN95 stuff (sensors mostly) of my 1994 engine to Fox stuff so I can use a custom harness which was designed for a Fox computer. I already have the Fox A9P computer on the way so I'm wonder if the SN95 stuff listed above will be compatible with the Fox computer. Thanks!

The MAF is identical electronically, but it does not have the flange to bolt up to the stock airbox. Moot if you are going to put a cold air kit on anyway.

Idle air bypass is also electronically compatible, but physically different. Might be able to get a Fox IAC to fit on a 94/95 throttle body, but not the other way around.

My MAF meter is already mounted on a CAI. I won't be able to use the IAB? Will the Fox computer read it or what would happen if I hooked it up to a Fox computer?

Are there ANY other differences in electronics and sensors that I will need to switch when swapping to the Fox computer? I alread got the distributor. I will be ordering a BAP sensor and a metal ACT sensor that mounts in the intake manifold. Do I need anything else? I really don't want to order something that's not needed or find out I need more stuff at the last minute? Thanks!

The IAC will work if you can get it connected. The shape of the 94/95 IAC is backwards from the Fox one, though, which makes it a chore to get it to physically fit in the right place. Might be able to get a 94/95 IAC onto a Fox TB with an EGR spacer, but without one it's just too big.

The only sensor difference I can think of off the top of my head is the IAT -- on the 94/95 it's mounted in the intake tube near the MAF. On the Fox, it's in the intake itself, and the computer knows that and expects it to read hotter.

I should be able to get the IAC connected. I am using a custom harness found on this page.

About the intake charge temp sensor, I am buying the metal one that goes into the intake manifold. I just used the a plug to cap up the hole in the CAI tube.
