First has anyone used a good hack to put a sn95 5.0 tps in a fox tb (It's 90° out) ?

Next if thats not worth it, I need to figure out how to wire the fox tps. Or if any one can help pin my way there that would be great! Build is still too far out to give voltage to the computer.

I have spent way too much time searching this, and keep finding my way back to the same write up that only refers to wire colors from a fox tb and a fox wiring harness.

5.0 sn 95 has blk/w, tan, tan/R


Tia for any info advice!

I am inclined to keep the sn95 tps because it reacts differently:

Sn95;
(Below #'s are ohms/c=closed throttle. O= open throttle)
A-b .4 c
A-b 4.0 O
A-c 4.2 c
A-c 4.2 O
B-c 4.2 c
B-c .4 O

Fox ;(
'g'= green b=black o= orange

G-o 3.1 c
G-o .2 o
G-b .4 c
G-b 3.2 o
B-o 3.4 c
B-o 3.4o

I don't know how big a deal it is but the 94 tps already has the resistance sweep the computer knows. Probably not a big deal to use the fox tps I just don't know how to wire it. Using an explorer tb because that's what the junk yard had, and I'm using an aftermarket fox intake manifold.

Ok looks simple enough.


Vref goes to vref

Sig gnd to Sig gnd

Org =vref. Brown/wht
Blk =Sig grd. Blk/wht
G= Sig rtn. Wht/gry


A Google search for the eec output for both cars and the tps plugs respectively made this possible

Put an SN95 throttle body on it. It's a little bit of money up front, but it saves you a lot of hassle down the road. Trust me.

Thanks,

So I think it was late, and I did not have the work light setup well is my excuse for mistaking the wire colors. Was worrying about nothing I think but there is still some inconsistencies. My correct colors are gry/red. gry/w. Brn/w. All the diagram show as you dicribed, and same as 89-93.

From a different read I soldered in the Explorer/fox connector as follows:

R/gry - Blk
Gry/w -grn
Brn/w - o

*well the correlating wires from the fox harness side of the plug.

I'll use the diagram tonight and duble check every thing by pin location.

Thank you!

Wish I could have used the sn95 tps but could not think of a good way to clock it.

The sn95 tb is a rectangle so it won't bolt to the intake

If the SN95 TPS works anything like the fox TPS, it simply takes a reference voltage at startup and adds a base value to that to signal WOT to the ECU.

I believe it's 2.71v added to the idle reference. So if your idle voltage is 0.7v, then all you need to do is surpass 3.4v to signal WOT to the ECU.

That's how the fox TPS works. I'm assuming Sn95 is similar.

You have to buy an elbow for it as well. Still worth it in the long run.

Intake manifold is temporarily in place for mock up. Got one in the mail.

Well , you are kind of invested now. I think that picture would have been helpful to see up front.

Sorry lol. Yeah I needed that straight run for the maf. I was scared of it not fitting under the hood, and figured that's why ford changed the design in 94 but, at current check the fox design does fit.

Why are we not switching to a slot style maf for a turbo setup? You must get tuned anyway best to use the right MAF for the application.

I did. It's upside down in a 2.6" pipe. I got the housing from a Mercury Fusion or something like that... cut it out of the air box. The maf is from an 05 mustang.
