AUTOmatic OBD2A to OBD1 convertion harness.... got some questions,
hello everyone.
a friend want me to tune his automatic turbod civic so we need to make a obd1 swap.
we got obd2a to obd1 conv harness and its seems to be missing all the 6 wires that controls the auto tranny.
so i went to FFS and 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 understand/MIXN'MATCH the wires....
thanks for reading
