Name those wires.

[Putter]

I need to know the function of the three wires listed below for Late T1 intake TPS wires.



Here is my assumption.

C = +5v
B = Signal
A = Signal Return (Ground)

Someone please verify this or tell me I'm completely wrong.

Thanks,

[Putter]

Anyone?

Anyoen know pinouts for the AIS also? As I also dont' have a factory pigtail for that either, and my replacement has 4 black wires...

i will look tommorow at work and see what they are. i have all data there. i used it for my a/f gauge and it helped alot.

Tps connector-
A-5v
B-signal
C-gound

If i have time later this afternoon i'll do the ais connector to ecm pin# for you .

[Putter]

Both of you guys are awesome, thanks.

AIS-

A-driver 4-yel/blk wire-----pin 60 at ECM
B-driver 3-vio/blk wire-----pin 59
C-driver 2-brn wire------pin 40
D-driver 1-gry/red wire-----pin 39

looking at the back of the connector, the notch/lock clip facing up, it goes

A B C D

do you guys have any diagrams that could tell me how to wire the tps sensor and the idle control motor for the 3.3 throtle body in to the old log style 2.2 wire harness

[Putter]

I wish I could return the favors and tell you, but I dont' have access to the books myself, hense why I started thread.

The 3.3 TB uses the connector I posted above does it not? If thats the case and you have a DVOM just measure which wire is +5 and which one goes to ground, and transfer the wires to the new pigtail.

The log style only uses a two wire AIS so two of the wires will need to be left out. I'll see if I can find that for you, I think I have an 86 log Datyona paper around.

Sorry, it took me so long to respond. Bill got it, but a good rule of thumb for TPS sensors is the center is usually the signal. Add to that the fact that the signal ground on our cars is always black with a light blue stripe, and you can figure out the 3rd.

2.2GLH: you can't really do that, per se. You need a logic module that can drive the 4-wire AIS motor. The old style uses a regular DC motor and a planetary gearset while the 4-wire uses a stepper motor. Basically, you need an 86 GLHS logic module and you need to run 2 more wires from it to the AIS motor. Using Simon's description of the AIS connector, you need to wire them to the logic module as follows:

A - pin 16 on the red connector
B - pin 20 on the red connector
C - pin 22 on the red connector
D - pin 18 on the red connector

[Putter]

Ahh, thanks for clearing up the difference between the two wire and four wire for me.

That brings up a new question. FAST says to use a GM type AIS its also a 4 wire same connector, would this also be a stepper motor type AIS and am I going to be lukcy enough that the Dodge 4 wire will be controlled identically.....they are very similar appearing...

[minimopar]

My guess would be that they are the same. There's basically two coils in there, so it's just a matter of connecting them to FAST in the right way so that it opens and closes.

[turbovanman]

GM and Dodge Idle motors are the same unless your talking Caddy, where they are actually electric stepper motors with an external plunger.

[Putter]

Thanks guys!

[turbovanman]

Sorry, I will add that they are wired differently, GM to Dodge, there internal wiring is setup different so its not plug and play, you need to move some wires around if using a GM motor.
