165 harness, 185 ECU - a little help translating pins?

[Dracov]

Soo... In an attempt to get my 165 up and running I came across a 185 ECU and have been working on an adapter harness so it'll plug in. I've got most of the pins matched up except a few I'm sketchy on and want to make sure they go someplace (or no place at all) before putting electrons through it.

Should also point out, the ECU I picked up is part number 89661-2B280.

ECU pins:
TE1 = Goes to T?
TE2 = I don't think there's an equivalent on the 165?
THA = THA1?
ACT - A/C amplifier, not seeing an equivalent on the 165
FC - Circuit opening relay - Not seeing an equivalent to this one either

And harness pin to ignore, just to make sure I'm understanding all this right:
FPU - Saw in another thread that this can be scrapped?

Thanks in advance

I don't know the ST165 but here are some details that will help you from the ST185 side:

TE1 & TE2 goes only to the diagnostic connector...
- TE1 is used to read codes and set the timing so you need it, however, TE2 is not really critical so if you don't have it on your harness, you can just ignore it.

THA is the air temperature located inside the MAF...

ACT is the signal that the AC circuit "tells" the ECU that the AC is on...

FC is the fuel-cut signal...

FPU? did you mean FPR?
- This signal control between the 2 speeds of the fuel pump.
- If you have only one speed on your fuel pump wiring you can ignore it, otherwise, you'll run only on the lower speed...

FPU is fuel pressure VSV on the 165.

FC is my primary concern since that's coming off the ECU and nothing on the 165 matches it in name.

All the other pins I've either found where they go or determined which ones can be ignored so far

I assume you already have this ST165 diagram:

That I do. Got the 88 BGB for Celicas, 88 Alltrac extra and the 88 EWD.
Also was referencing the 5th gen BGB off another site to get the pinout names and am using http://st165turbo4wd.hp.infoseek.co.jp/ecu_pinouts.html as another reference.
The adapter harness is finished right now. Didn't permanently affix the wires to the receptacle in case I need to change something but I think I have everthing that's needed
