ok first off thank you for your time..
I will be posting the swap in some detail...and in "
BOLD" will be questions regarding something related to it....each question will have a

im currently doing a ae111 20v 4age Blacktop swapping from a 1.6 4a-fe on my 97 corolla...
i did about 5 days of research and downloaded a WHOLE bunch of PDF files before i even bought my motor, but it seems that i have taken the wrong turn from my original route lol...
i was planning on using the 4age engine harness, then cutting/tracing/splicing to my body harness and junction box....
but, my brother convinced me (having more automotive experience) that i should just use the stock 4a-fe engine harness, that way, everything WILL hook up...and whatever wires and sensors we dont have, well, hook up directly to the ECU....
well, not thinking about it, i agreed..
so far, all connectors from the 4a-fe wire harness plug in perfectly into the 4a-ge sensors....only sensors missing were a couple oil sensors in the front of the 20v...
the TPS sensor for the 4a-fe was near the dizzy side, so we had to cut and splice wires to reach the TPS sensor for the 4a-ge, which is on the belts and pully side...
Question #1
on the Dizzy: instead of cutting/splicing the 4a-fe dizzy connector (4 wires)to the 4a-ge connector (4 wires)...can i just hook it up directly to the ecu?
i.e grab the ECU pinouts for the 4a-fe and move wires around to match the 4a-ge pinouts
------------------------------------------
So we drop the motor in...and when i go compare the ECU connectors..they were the same...but the pinouts were different!!! HOW COULD I HAVE MISSED THAT!?!?! i knew it, but it slipped my mind....
luckily, the "C" ecu connector (4a-fe 22 pin) is exactly the same as the 4a-ge (22 pin)....so i have about....roughly 15-20 wires on the 26 pin and 16 pin?
so now, i plan to trace wires and just manually rewire the pinouts from the 4a-fe to the 4a-ge...at least thats my theory.....
Question #2
4a-fe>4a-ge harness:
So, can i still use the stock 4a-fe harness instead of the 4a-ge, and expect the same outcome?
theoretically, the harness is just wires, the difference in specs would be individual sensors and the ECU...correct?
-----------------------------------------------------------------------
today i went the the junk yard and to my surprise, there was a ae92 16v 4age...i thought to myself..OF ALL THE CHANCES?! THIS MUST BE A SIGN!!!!!!!! lol and how i was so sad....this great car..in the junk yard...i almst shed a tear...back to topic...
when i ordered my engine..it unfortunately didnt come with an ighnition coil..so lucky as i am....the Ae92 still had its ign. coilack...so i took that..along with its throttle cable...(my stock cable was too short)
Question #3
Ignition coil: Can i use this ignition coil for my 20v 4a-ge Bt?
i was told, since this is a 20v...the ign. coil would fire differenty because of the 5th valve...
Question #4
Sensor near coil?
since my 4a-fe didnt have an external ignition coil pack...the 4a-ge harness has the Ign Coil connector (Fig 1. blue box)...so my question...
what does the "sensor near coil"(fig 2. Red box) connector go to...i obviously dont have a sensor near the coil...and do i need it for my ignition system?

i really cant think of any more questions right now...just these 2 and a half lol....any help or feed back is GREATLY appreciated....please help..THANK YOU!
