Auto obd2a to obd1 question,
 

sup, i need some help/advice on this one.
my friend asked me to tune his 98 automatic turbod D.

so i got a random obd2a to obd1 harness and its missing the AT related wires,

i looked at FFSQUAD and the missing wires on the obd2 side are:
connector C:
TMB (AT related to tcm)
ATP (park and N or clutch switch)
ATCHK (detects tcm signal)
AFSA (AT tcm related)
AFSB (AT tcm related)

connector A:
SLU (brake lock)

any one know how/where to wire them on the obd1 side?

thanks

Re: Auto obd2a to obd1 question,
 

if i remember correctly, it wont work. you need a obd2 ecu to control the 96+ trans because it different.

tell you faggot friend to convert to manual and stop being a -----. unless he has one leg of course, but thats the only excuse.

actuely yes, my friend is handicapped ::)


i dont see how they are different, mechanism is the same,
as far as i remember, when i used to work for a honda dealer we installed "obd2 trannys"(used ones) on 92-95 civics.


this is what i came up with, (copied from my massage on HT)
i found the 6 wires that are missing on both sides of the harness,
But the acronyms for the pins in obd1 and obd2 are not the same so i'm having hard time mix & mach them 6 wires.

this is what i come up with:

obd1 side acronyms :
CON A:
-pin (18) TCM ???

CON B:
-pins 3 +4 (A/T related) ????
-pin (7) clutch switch + park & N
-pin (9) TMA/FAS + starter switch

CON D:
-pin (18) interlock control unit

And to the OBD2A side:

CON C:
TMB (AT related to tcm)
ATP (park and N or clutch switch)
ATCHK (detects tcm signal)
AFSA (AT tcm related)
AFSB (AT tcm related)

CON A:
SLU (brake lock)

please, help me miv & match :P
