obd1 ecu w/ obd0 auto trany

[Diemaster]

how is it done? svoboy said it was easy but i want more detail in here.

[SVOboy]

Take the a19 pin (which is for the torque converter) and wire it up to power with a switch. Flip the switch on when the car warms up a bit and then turn it off when you turn the car off. Piece of cake.

[Diemaster]

is a19 obd1 or obd0?

also if u could help me with the P-N--- and ---D-- inputs.

also i thought obd1 autos had a seprit TCU for the trany. like this:

****, they might, hell if I know.

The obd1 ecu has both full lock up and partial lock up. Our trannies only do full lock up, so I only hooked up that pin.

The p n and d stuff is in my harness somewhere, I wired it up, but I never had an issue with trying to figure how it worked so I didn't pay much attention to it. I can figure it out if you want.

[Diemaster]

yea i'd like that. as i'm making my own harness.

[SVOboy]

I'll figure out what pin it is then, just remind me tomorrow when I'm not so damn tired and I'll post of the wiring stuff for both our cars and obd1 stuff.

looks like obd0 A8 goes to obd1 A19 ... maybe A17
i just skimmed this thread...i think this is what you were after...

ooowee i matched another one...this is like mahjong
obd0 B12 >>> obd1 D18 ::: both are white/red

[SVOboy]

I think it's a19, lemme check though. One will ruin the tranny the other will make it work fine, :p

is that for DPFI? b/c mine was like that till i went MPFI. on MPFI it's A10 :)that i know for sure.

[molecule]

the mitchell manuals are split up into TBI (throttle body) and PFI (programable fuel)...
so yeah...i guess a little incomplete...
maybe if i look up on the d16a6 si it would be different...

[Diemaster]

heres what i've found out.

obd1 (color) -> obd0
B7----(grn)------B7 P/N in
B4---(grn/blk)---B11 D4 in
B3---(grn/blu)---(add) D3 in
A19--(yel)-------A8 TC lockup (i hope your right svoboy.)
A17--(grn/blk)---DONT USE see up svoboy.
D18--(wht/red)---A10/mpfi/ps9 / B12/dpfi (interlock cntl)

as soon as helga is better and not beeing so *****iy on her period i will test the above.

[SVOboy]

The auto ecu will just give you a code since you're not using the partial lock-up and it'll be angry.

You should just wire a19 to 12v and be done with it on a manual ecu. You can ground out the park switch inhibitor thing so you can shift around without pushing in the lock.
