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!

- Yes
- Yes
- Yes

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.
