Ok this is for my 93 RX-7. I have a 2000 PCM and harness(automatic) that I need to work on a 93 RX-7 with an LS6. I found these pinouts

http://www.ls2.com/boggs/torques/00pinpcm.htm

And now to the questions..I know I need different plugs for the t-56..question is after I get these plugs..where do I wire them to?...Also looking at this diagram I wanna take the following wires out of the harness and recover to and clean it up alot...(this is gonna be long)

On the BLUE connector I want to get rid of PINS:

25 H02 low-bank 2 sensor 2
28 H02 low-bank 1 sensor 2
65 H02 high-bank 2 sensor 2
68 H02 high bank 1 sensor 2

41 EGR
47 EGR
55 EGR

45 AC

Now the ones on this one I wasnt sure of were:

53 Trans Temp sensor ground
70 Low Oil Switch Level(there isnt a low oil light in the car)


Ok and now for the red:

2 TCC
4 AIR pump
6 Trans fluid pressure high
8 Trans fluid pressure low
13 Cruise control
14 AC stuff
17 AC stuff
18 AC stuff
34 EVAP Canister purge valve
36 AIR pump
37 Cruise control
42 TCC
43 AC stuff
45 Evap



And these ones im not sure of cuz im sure some of these need to go to the T-56 connectors:

47 Trans Shift solenoid B
48 Trans Shift solenoid A
51 Trans Temp Sensor signal
63 Trans Range Signal A



If anyone can help me with this id GREATLY appreciate it. Thanks-Mark

 

Keep the wires going from the VSS to the pcm. Get rid of all the other tranny wires. You only need the two VSS wires. They should go to C2, pins 20 and 21.

 

What pins am I gonna need for the T-56? Like the reverse lock out and stuff?

 

You can use the factory vss plug on the auto harness, it plugs right into the t-56 sensor.
As for eveything else...why do you need it? You dont want a skip shift, and reverse lock out is pointless. When I put my t-56 in I only used the vss, I didn't use anything else.

 

well the reverse lockout helps me. it will never let u go into reverse while going forward! works great.

 

Reverse on my shifter was about 3 inches away from 5th gear. You could'nt shift into reverse if you wanted to. I had to TRY to put it in reverse when I wanted to go into reverse. Maybe I had a different shifter?

 

ok great. the vss is the light green and purple..i left those two.

 

Oh BTW its a 99 harness..I made a mistake..luckily all the pins are the same!!!

 

I took the reverse lockout wiring off my car and never even came close to trying to get reverse while rolling forward. Just remove all the wiring and have a cleaner, easier to install, harness.

 

I did..now im stuck with #53 on the red plug..its the spark retard signal..and it was in a rectangle plug that houses the orange PCM power and tach signal(white) wire...the only wire left on it is that gray/black #53..and it seems like it connects to the body of the Fbod somewhere cuz the plug is VERY close to the PCM connectors.

 

 

When I get home from work, I'll check my diagrams and see what it runs too. I don't think you'll need it for anything, but I'll let you know in an hour or so.

 

That wire used to go to the Electronic Brake Control Module. You can get rid of it.

 

Thank you very much. I think I can get rid of the whole plug.

 

Yes you can. You might want to trace the pink wire to see what it powers.

 

haha yeah im sure its to something useless though but ill cut the thing back open and look.
