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?

i would NEVER EVER use those.
do you REALLY wanna trust the brain of your engine to those crappy things?

I used them when I installed my CD head unit and haven't had any problems, but you're probably right, the ECU is alot more important and the risk is probably better not taken... guess I have to learn to use a soldering gun now. *sigh*

i would actually use an electrical tie-in for it since thats what the connector is used for.
ill get a pic of it later

^^^^^ i think they are called "scotch locks" or something of the sort, and with the wire nuts, if you do choose to go that route tape up n over the top of them to the wire so they wont be as prone to spin off, soldering is by far the best way, not too hard to do, practice on some spare wires if you feel nervous

yes its a scotchlock
but technicly its an "Electrical Tap Connector"
heres a pic of it and i believe this would be the cleanest way of doing it but a more permanent way is always a good soldering. make sure you use rosin core solder tho.

I soldered mine when I installed, I don't wanna take any chances. I've had those scotchgard things come loose before on other things on my car just from vibrations and I tightened them reallly tight when I installed them.. (for lighting and such).

sorry for bumping an old thread, but was wondering if I did something wrong since the knock portion of my S-AFC has been reading 0 all this time and hasn't fluctuated since.

check your wiring, then follow the instruction manual to set it up properly.
the knock sensor wire is very easy to see on the ecu plugs, its the only wire that connects to a plug that has clear sheilding (on my 94, anyway..lol)

I have the same problem. Alex - You wanna come over this week and we can see if we can figure it out? I have that new garage and all my electrical tools and supplies moved in already. It's alot closer to you also.
BTW - I have my ECU pin out diagram but yours will be different.

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.

well, technically, living in california we have earthquakes so you can't say there is NO vibrations at all

but it's ok. I bought a spool of wire and some solder, and found my dad's old soldering iron, taught myself to solder, then went and did it on my car. I only had one crappy connection but after I went back and resoldered it it was ok and since then, no problems whatsoever.

well , i know this is an old post but is that a shift light in your tachometer ? ( that led )

old thread revive. Does anyone have pics of the wiring?

will this wiring procedure work with the apexi afc neo?

is the throttle signal the same as a knock sensor? The neo has a throttle signal. Oh and the celica is a pressure sensor type cpu right? should I use the 3sfe wire diagram since the 5sfe wire diagram aren't in the booklet?

yes the 5S-FE is a MAP based system.

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.
