Swift ECU 33920-72C1 pinout

[fixkick]

Thanks for the insights. I had no idea this stuff was so rare nowadays.

its not that the ECU are so rare, as they are horded,
ever use google and see those huge prices on ECU, ? $500 and up. hording does that and most are by wrecking yards.
Its rare for these reason:
lacking the VIN code, matching parts is hard, so Ill look in the EPC parts list.
i search your 72C12 and it was in the SF:116 car (means swift cultus and more)
The car is MK2 series in Europe I guess. type 2 engine 1.6L only.
it was used in 15 Euro counties and australia.
the market codes are, 02, 15 to 19, 21,22,25,26,39,53,65, and 66 , 68
you can look that up here
02 is england
70 poland is not listed as sold there, oops
66 is Hungry plant swift,
68 is Ireland
22 is German

lacking the VIN its is impossible to know what country. the other ecu codes (mitsubishi?) are secret to Suzuki, ask them? yet.?
so find a swift book from any of those countries,
US would be in english. so E02, is best.
that ECU was never used in the USA (its illegal here, car or engine or its controls)
E02 swift boot, MK2 era.
off the code book
model code vin (4th./5th)code 63 is your engine, 1.6L MT 2wd, yes they had 4wd ecu and cars
Vin ends in 02 is England UK car and engine and ECU
same as yours.
as for year, best I can tell 1993 to 96 year.

the market code list
is here

so buy UK swift book 93 to 96,is my best guess. 1.6L
