Hey guys, I did a search and couldn't come up with anything. I need a Pin layout of a pre-98 Zetec. I'm trying to see if I can make the homemade shift kit the ZX2 guy's are making, And I can't find a PCM layout so I know what wire i need to splice into. Thanks, -Josh

If you can receive a FAX, I'll send you the diagram. Do you Need 1995 - OBO I or 1997 - OBO II

Nope, I don't have a fax machine, Sorry.
I need it for a 96; OBD II
Actually, I just need to know where/what color the wire for the EPC is

Here you go...

Just ignore the Focus PCM stuff. I was trying to see if I could re-wire a Focus PCM so that I could swap out my CD4E and put in a 4F27E.
The data was copied right from my service manual. It should all be correct.
BTW, what are the ZX2 guys up to?

I'd like to know as well... A shift kit?? They must be doing something with a sensor input to raise line pressures is my guess.
Must be that jumbly-wumbly thing happening again.

Yup, basically they use a 10k ohm resistor on the EPC wire, it stiffens up the shifts and raises the shift points a little bit, you can even use a 20k ohm reistor to stifen them up even more. You can run a 10k ohm 24/7 20k ohm you use a switch and only use it when you have to.
all the zx2 owners that have done it have had great results, and most can chirp second reguardless of RPMs
Buttonpuncher, thanks alot man! I'll have to download a Excel veiwer to veiw it, doing so now. Thanks again though!

So they're putting it across the EPC solenoid wire? AFIK, the CD4E doesn't have a pressure sensor to trick, only the TSS (turbine shaft speed sensor). If it's the EPC solenoid, that's kinda dangerous. If you shorted it out accidentally, you would fry your PCM's output transistor(s) and possibly break your ATX. Runaway line pressure is one of the main causes for killing a CD4E.
If you don't find an Excel viewer... You are looking for Pin 81. The wire should be black with a red stripe. It would probably be easiest to tap into on the connector on the ATX instead of at the PCM.

Buttonpuncher, thank you so much! i just got that open. That's a HUGE help to me..
I can do this, its listed at 81 in the list, the black/red wire.
I'm also tempted to do the POTs mods, which basically tricks the ECT and IAT, dumps more fuel and advanced the tming (guy w/ auto zx2 went from 17.4 to 16.5 with JUST the pots mod)

Both of those thoughts came to mind for me as well... The ZX2 automatic is pretty tough. Application for application, much tougher than the Contour CD4E.
Keep us updated.

Not to be a nay sayer but people have tried the POTS mod on the Contour PCM and it causes alot of havoc. The PCM relearns very quickly. It still might work in a racing situation with limited use.
BTW, it would lean things out and add more timing. That's what the PCM does when it's getting really cold air. When its really hot out, it richens things up and pulls a bunch of timing to prevent detonation. That's why your car can be a real dog on 100 degree days.
