Not sure what you are trying to do.... Are you trying to find like a spade type connector so you can plug into the stock TPS switch harness so you won't need to cut it ?

I prefer the latter, but am ready to go with the previous.

I just went to look at the plug going to my "regular" TPS - if you want to save it without cutting you may be able to use the smallest blade type connectors. I'm not talking about a OEM style plug but individual crimp type connectors on one wire per connection ( 3 total )

There is one blade type male connector sold at auto stores and maybe even RS that is about 1/8 wide. You would need to cut them down with a pair of sharp wire cutters and then file them smooth and flat.
Once trimmed you should be able to insert them into the factory harness that plugs into the TPS. The wires coming from these connectors will go to your Variable TPS

You can also hack up the stock TPS and solder wires as shown here . https://www.miataturbo.net/forum/t23979/

Can't you just intimidate the connector into fitting? Chuck Norris wouldn't have this problem.

:giggle:

I'm actually just a 14-year old who lives in his grandmother's basement. :cry:

That explains the toys in the avatar !!!! :eek5:


BTW these are the connectrs that I was referring to http://i261.photobucket.com/albums/i...rimpSwitch.jpg

meh, too big and wrong sex. I think DIY may have something, they did before.

like i said, go to autozone, buy a pack of .090" female spade connectors, insert, fill cavity with silicone.

my local vato zone, oreilly, advanced, and napa don't have those. I can't find them in google either, only soldering tips.

wtf?

Has anyone used the Ford Escort GT VTPS from a 98 GT ?

I just came from Advanced Auto and the GT VTPS is cheaper and it is in stock .

the Duralast TPS 0201 is about $30.00 vs Aprox $17.00 for the Ford one

What do you guys think ?

If it fits, run with it.

Even with the OEM '90-'93 Auto TPS, it's not a plug-n-play mechanical matchup for the MT TB. On the manual throttle bodies there's a long shaft which engages a hole in the throttle switch. On the auto bodies, the shaft is short and has a flat plate with tabs protruding from it, and these tabs engage the TPS.

When I converted mine, I cut down the shaft on the throtte body, tapped it, and then used the lathe to fabricate both a small, mushroom shaped piece to sit on the end, with a small stud sticking out to engage the TPS. I then lathed a collar to center the TPS on the throttle body and space it properly. (I used a Honda TPS, but it'd be basically the same gig for a Miata TPS.)

Long story short- no matter which TPS you buy, there's going to be some fab work involved. So if you've got a line on a cheap new Ford part, might as well get it and make it work.

will it fit on the throttle body shaft keyway?

I had stopped at the auto part place on my way from driving my father to the Dr so I was not prepared to size things up...

It seems like I am going to take a leap of faith at some point - Been reading the threads but I've not decided yet on anything.

I'll probably take the stock TPS off and drive to the auto part store and compare the pieces right on the counter.

I'm just trying to comply with the design directives. Cheap, Easy to implement does not require taking the TB off the car and, Robustness oh and did I mention cheap?

Now, if I get a TB from an auto does it just bolt right on ?

That's what I was going to ask. If you have to get the TPS from an auto anyway, why not get the whole TB while you're there? Save the fab work.

I went through duralasts catalog to find the TPS I used, I really wish I could find the part number, because the fab work took me about 15 minutes. IT consisted of marking the postion, removing the guts, screwing two screws and soldering three wires.

really it's not much different than Ben's write-up, i just didnt have to cut the shaft or cover.

Scott, I do not like your new avatar. It scares me.

In the movie The Amittyville Horror there was that evil devil hound that peered out of the attick window..... :eek4:

I have some numbers from another thread Duralast TPS -201 , 4164 and 452 as posible candidates.

These are the threads that i have saved on the subject but can't seem to finish reading because of other responsibilities :vash:

The threads probably cross polinate but maybe it will help someone if they are all in one place .

I remember reading someplace tho, that the VTPS from an auto does not bolt on to a 5 speed TB because the TBs are different between the two cars ( auto and 5 speed ) That seems to be what Joe describes in the previous entry.

When I pick up my evil spawn from school I'll be able to tear off the TPS and see what it takes to convert.

its not his fault, he really wanted those cupcakes.

Hustler, i can send you a few .070 contacts, you'll have to force them on, but that's what I had used.
