Power FC arrived today, Newb needs help!

I just got my PowerFC from rx7store.net today.

I have read (yes, and searched) but I have found conflicting info for the installation.

Do wires need to be cut for install or is it simply plug and play?

Some people say some EGR switch and EGR valve wires need to be cut, and some don't.. but I'm not sure.

SO...
Do any wires need to be cut for installing the PowerFC in a '93 FD??

As always, any input is greatly appreciated.

Right in the sticky.


JDM cars do not require the removal of the wires.

Right, I read that. I have a non-jdm left hand drive fd though.

It says:
If you have a non-US FD, you most likely won’t
have to cut these wires, as the wiring is the same as the Japanese market FD’s.

Therefore I would assume I DO need to but them.


It also says:
There are 4 wires that need to be disconnected from the wiring harness for the PowerFC
to work properly. These 4 wires are for extra emissions devices that were added in the
US market, but weren't in the Japanese market.


From this I would assume that the 4 wires DO need to be cut.

Basically I'm just looking for confirmation that I do in fact need to cut wires for the installation.

I would prefer not to cut up my Fd!

If you read the next paragraph it will tell you some options so you do not need to actually cut the wires, But here it is, anyway taken straight from Dale Clarks PFC FAQ.....

There are different methods for accomplishing this. You can either simply cut the 4
wires on the stock wiring harness and tape the ends up, cut the wires and splice an
electrical connector onto the loose ends so they can be quickly re-attached, pull the pins
out of the wiring harness' connector, or break the pins off on the PowerFC itself.
Personally, I'm not a fan of breaking the pins off - it's too easy to harm something else or
break the wrong pin off. Whatever method you choose, make sure to insulate the bare
electrical connection so it doesn't short out against something else.



The reason why I wrote JDM cars do not require the removal of the wires is so you know why some people may say the wires do not need to be cut.

You cleared up my confusion.

Ok so I just unbolted the stock ECU....

does anyone have any tricks for taking off the 4 connectors???

I'm 6'4", so getting in there isn't very easy!

I'm being gentle with them, but is there a trick???

Tricks, tips, anything is helpful!

^A flat head very gently? That's how I do it anyway. Just be careful!

push the connector in first, to seat it properly. Then push down on the tab and pull out. It may take some force or it may take some wiggling.
