Swapping throttle position sensors from the later model engines into the early model engines don't do anything performance wise (as far as I know, but what do I know) and may be a real waste of time. I began using later model plugs because they look cool and much easier to deal with. Unless you like running older model connectors (I really hate dealing with clips) or you live in BFE where all the old TPS are not available from your local parts store. But if you're like me and have nothing better to do than redoing your harness on a kit car or on a race car, this could be for you.But rather than grabbing another throttle from pick your
As you can see the difference between the two plugs. Just like in preschool, the block cannot go into the hole.
And since the rheostat is 90 degrees off it's not a straight drop in.
Here's key to the whole thing. Note the early style is on the right side.
Old style
New style
Once done, reset the TPS. And you're set.
Oh I tried to do this trick on 20V t' bodies. It doesn't work so don't try.

yes indeed .
ive done this too many years ago .
but what do you mean it doesnt work on 20v itb?
for the itb conversion you need the 20v tps which is counter clockwise.
the 16v tps is clockwise .
no match there .
by the way ...
ive done a 20v st itb on a 16v ae86 4age with stock ecu.
yes its perfectly doable...
BUT the TVIS must be used along with the itb's and the vacuum outlet that connects map + fpr must be used as is .
there is somme kind of restrictor inside it that helps keep the map signal correct.
i just used a safc apexi .
my afr is just like a normal 16v ....
stock trumpets
stock everything .
car is smooth and 100% drivable.
it even passes emissions test . afr idle 15.5
after 4000 TVIS is on and brings out its best ...
