most of the wiring should be the same, EXCEPT that on the silver top there is an AFM (air flow meter) and the Black Top there is a MAP (manifold absolute pressure) sensor...

ok, two questions... and one comment...

first the y/g coolant temp wire is only for gauge purposes right? how did you guys run it? there was no way i was clearing that sensor past the firewall...

second for the ignitor which wire did you splice into? i just went with the straight black one that i traced back to the blue dash connector on the 20V harness...

lastly for my alternator circuit i used the stock ae86 stuff... did your guys's just plug straight in? i didnt not have to change anything and it worked with the 20V alternator...

i have a silvertop with all the wiring, and im planning on using a blacktop ecu, is that possible? if so is it the same procedure as the one in this thread? if not, does someone know how to make it work? my only intensions for this is to use open throttle boddies with velocity stacks.

will be tough... pretty sure the pin outs are quite different...

first main problem is that the blacktop is run with a MAP sensor, silvertop runs with an AFM...

you will have to pin yourself where the map sensor wires would be, and not sure about the rest of the pins, look here...

blacktop - http://www.club4ag.com/faq%20a...E.jpg

silvertop - http://www.club4ag.com/faq%20a...r.htm

read through them and compare every pin... thats the best i can do for yah...

bro. get a map sensor out the junkyard there's a thread on here to which you need. all you need then is that blacktop ecu and an Air temp sensor.. if you go to the tech section you can see on moto-p's writeup the sensors you need. there is a thread about ignitors in this section that tells you what car you can pull the map sensor from... and for the rest it's easy as **** so dont believe for a second it's a tough job. nothing is ever tough it's just the mindset you have going into it..!!

blk/orange - to ae111 coil, and to the blk/w on the igniter that goes to a split-where it meets all four injector positive wires. there will be a sixth wire you can run back to where the blk/orange meets the coil.

what does this mean? ive traced the blk/white wire from the coil and ignitor, and from the injectors, found the split and fount the sixth. Now do you cut the 6th where it runs very close to the ecu plugs?

I'm stuck on this..... anyone? anyone?

Also, for

Which black/white wire do I need to tap into? there are two...

Engine and ECU loom only, you wire it into your AE86 dash loom

hey i just got my 20v silvertop and I am wondering what connectors you have to cut because most of them go to the ecu and I shouldn't have to cut them?

We have a car here that we're doing a 20v swap (silver top) on. This post is very helpful to me however I have a question about the 22 pin connector on the 20v ECU. What are people doing to hook the necessary pins to this ECU? Is the factory connector available from Toyota? My understanding is that it's part of the 20v's body harness (which we don't have)

Any help is much appreciated.

I went to junkyard and get that connector from mid 90īs corolla powered by 4A-FE... I think it could be same at all that age gasoline toyotas. And connector to the engine room accessories( wipers, waterpump for windscreen), I got from Corolla ee90.

Did you guys manage to wire in the check connector plug?
Can someone be kind enough to share the diagram where the wires go. I am having trouble with my conversion because some of the diagnostic wires go to the body harness of the AE111 and dont know where these wires go.
Cheers...

So im guessing this uses the std AE86 engine bay fuse box or did tyou guys use the 20v, im thinking if I use the 20v main big fuses 3x of them then just use the 16v normal stuff, so 20v battery terminals etc then splice into main relay

Hello, I was wondering if you could clear something up for me. I was curious about what wire in the kick panel I need to hook up to my blacktop ecu's SPD terminal. I see two potential candidates, so I'm not sure which of the ones it is. I have a post about it at the end of this thread: http://forums.club4ag.com/zerothread?id=32439

sorry for posting twice, but I really wanted to confirm this with somebody who knew.


UPDATE:
Nevermind, problem solved. Check the post I refer to above for a clear guide to getting your SPD wire hooked up properly.

Hey does it have a lower rev limit or anything like that? Or is it just a matter of bypassing the neutral start switch? Cheers

The blacktop auto ecu will be ok. When you change to a manual gearbox you can disconnect all of the auto trans connections except for the neutral start switch (NSW) which is pin number 22 on the 22 pin plug.
