Another update......been a while i know
I made a disturbing discovery........ everything mechnical is 20V Blacktop..........everything electrical is 20V Silvertop
My throttle bodies ARE Blacktop, but the MAP port is blocked off and looks stock, will upload image when i can.
My ECU is a tuned SILVERTOP, the loom is a SILVERTOP...... the actual engine is BLACKTOP.

Cheapest and easiest option is to fix the original ECU, I'd prefer a professional did it, but i will do it as a last resort. Other option is to buy BLACKTOP ECU and loom (one plug difference) and cut it up, which will be expensive and time consuming.

Still unemployed.....

I want to get my hands on a 4AGZE, once i get the money, and after this engine dies.

Dont really know if i should still be continuing this build

you got quite the Frankenstein motor lol
and luckily for you the 4agze is made for horizontal configurations. It would almost be plug and play if you went that route. Trying to convert mine has been a challenge as the entire cooling system on my engine was shot and had to be bought again and not many people part out just coolant lines when they know they might need them again.

I bought a new ECU ,this time a proper BLACKTOP ECU, along with a 22-pin plug to suit. Also scavenged a MAP sensor an Air Temp sensor from a 4AFE, i've heard some controversy as to whether a 4AFE MAP sensor will work on a 4AGE 20V, but i don't see why it wouldn't.
overall fairly cheap, but time will tell, hopefully it will arrive before next Sunday, as i am entering a local motorkhana / autocross, and id love to drive this instead of renting a club car ;(
If anyone has any advice on re-wiring / repinning an ecu plug, let me know
(Really hoping that none of the caps have leaked in the new ecu)

Currently wiring and plumbing new sensors.
Could any Toyota boffins please let me know if this will work
VSV = VSV for EVAP (emissions)

I'm also wondering if I should just remove the wires from the old plug with the pins, and then insert into new plug,
or manually attach each wire to the new pin for the new plug
(for ECU)

MAP should have it's own, dedicated vac line behind the butterflies. On a blacktop manifold, there is a special nipple just for the MAP. It draws vacuum from each cylinder by way of a channel in the manifold... but you should be fine drawing from only one cylinder.

You need to get rid of the T. Connect the MAP to the vac port on throttle 4, which you have the thick blue line drawn on.

The green line from the vacuum rail is correct, that is for the VSV. I'm not sure what the other line marked VSV is. There should be two lines coming of the VSV valve. One goes to the charcoal canister, and one goes to the nipple on the vacuum rail (as you have it marked).

The airbox one is unnecessary. That was for AC/PS idle up. Just cap it. The line to the airbox should come from the nipple on the back of the valve cover instead, and is part of the PCV system.

Oh, and to clean it up a bit, you can twist the ISCV vac line nipple so it faces down towards the ISCV, instead of sideways, as seen here (step 15+16): http://www.garage-annex.com/kitmanual.html

Thanks for that Oggy, ima be onto that asap.

The whole ECU plug this was the last straw, i refuse to use this loom anymoe.
And to that effect, im now in the market for a new harness/loom.

So if ANYONE hears of a usable 4A-GE 20V Blacktop wiring harness/loom for sale, pls let me know.

Recently i bought ANOTHER corolla, this time an ae82 twin cam seca liftback. Rebuilt engine and not even started, so this new car is first in line, and the white seca has been shunted aside for now.
I am most definitely NOT going away from this car, i am merely pausing until a new loom is found, and this new car is run in...

So don't be surprised if this thread isn't updated for a few months...
