how to install a SAFCII in a 94 GT Options

[presure2]

hey all installed my SAFCII today, figured id make a quick writeup on it, for future refrence...so, here it goes.
youll need:
10mm wrench to remove battery cable
good soldering iron with good solder
wire strippers
electrical tape
14mm socket, wrachet and extention to take out your seat if you want to.

To wire in the SAFCII is actually really simple, it just a handfull of wires that need to be tapped into and one that needs to be spliced.
So, lets get started.
DISCONNECT THE NEGATIVE BATTERY CABLE!!!!!!!!!!!!!!!!!!!
first you need to get crunched up in a ball, and wedge yourself into the little space in front of your passanger seat, look behind your center console, and find your ECU...if you cant find it, or dont know what a ECU is, STOP! you shouldnt be installing this!! hahah...or you can just take your seat out, its only 4 bolts...makes it much easier, lots more room to strech out and be confortable.
you'll have a 26pin connector, a 16pin connector, and either a 12 or 22 pin connector depending on weather you have a manual or automatic, (looking from left to right.)
pull out the 3 connectors, and reach behind the console and unplug the remaining connectors, and free up the harness so that you can have some room to work.

now, take the 26pin connector in your hand, look closley at the wire side..you'll notice they have a number on each corner of the plug, coresponding to a pin # on it. find the #1, and from there follow to pin # 3 which will be a black wire with yellow stripe. this is your RPM wire(ignitor) take your wire strippers, and about 3 or 4" from the ECU, just strip back about 1/4" if the covering, without cutting the wire.
take the green wire from the SAFC harness, twist it around the blk/yel wire, and solder it in place, then tape it up.
next find pin # 14 on the same 26pin connector. its a brown wire. this is your ground. your gonna connect 2 wires to this wire so take your wire strippers, and again strip back about 1/4" of the covering 3 or 4" from the ecu. take the BROWN wire from the SAFC, twist, solder, tape. then about another 2 or so inches back strip another 1/4" section of covering from the same wire. take the BLACK wire from the SAFC and twist, solder, tape. THE GROUND HAS TO BE HOOKED UP THIS WAY!!!! we're done with that connector.
take the 16 pin connector, find the #'s again. find pin #2. its a grey wire with black stripe. this is the map sensor. about 4" back from the ECU cut the wire and strip back about 1/4" from both sides. take the side of the wire that comes from the engine bay, and twist it together with the white wire from the SAFC, again, twist solder tape. then take the ecu side of the wire, connect with the yellow wire from the SAFC twist, solder and tape.
next , find pin# 11, its a black wire with white stripe. thats your TPS sensor. strip back about 1/4" of the wire covering, take the grey wire from the SAFC, twist, solder, tape.
next, find pin# 13 its a clearish white wire, thats your knock sensor. strip back about 1/4" of the wire covering, take the purple wire from the SAFC, twist, solder, tape. we're done with this connector.
now if you have a manual, take the 12pin connector (22 if its a auto) find the #7 pin (#12 for auto) its a black wire with yellow stripe. strip back about 1/4" of the wire covering. take the red wire from the SAFC, twist, solder, tape.
THATS IT. reconnect all the plugs, plug the SAFC into the harness,and reconnect the battery, but DO NOT start the car yet. put the ignition in the "on" position make sure nothing is burning or smoking..lol then follow the setup directions in the SAFC manual. ENJOY!!
feel free to hit me up on AIM or whatever with any questions you might have, happy to help!

sorry to revive an old thread, but couldn't you just use wire connectors like these:

instead of soldering, so that it's not as permanant of a job?

those connectors are for home wiring only. they are made to twist thick gauge wiring together inside of a house where there are no vibrations or movement to deal with .

you really have to solder the safc in. anything else will come loose and cause the car to stall out.

Just strip back the wire you want to tap into and poke a hole through it, then insert the wire you want to connect through the hole wrap it around the wire you want to tap and then wrap it with electrical tape. Done! I did this when I installed my car starter and I have never had a problem. That was three years ago.
If you want to connect two wires together just get some red butt connectors from you hardware store but make sure you crimp them well enough that you can't pull them apart then wrap it in electrical tape. Always wrap any connection in electrical tape. Then when your done bunch the wires together and wrap them all in electrical tape. Do not use duct tape or masking tape these Are no good and those twisty things are no good also don't use scotch locks as they are awful and will cause you headaches.
