Anyone got any prices or links dunno what I'm looking for, anything else I'm fine electrics a no go lol
Yours is a phase-2, so you need just the KKL cable mentioned in post#3 of this thread. It has wiring adapted to connect pin-7 to pin-3, because FIAT/Alfa use pin 3 for the airbag ECU, pin 1 for ABS, pin 9 (I think) for the climate control, another pin for the hood ECU, and another for the CODE box, etc. That cable looks like it will do everything, so is an excellent way to avoid fiddling around with soldering wires on. It's so cheap I think I'll get one myself. Thanks GTV_Blue
I bought the three-adaptor set from Gendan.co.uk, so I'm ready with my coloured plugs Gendan style. These can be used in conjunction with other KKL cables (like mine) that don't have the switch. This approach will also work with the newer cars I work on, because I have an ELM327 cable as well (not needed for the GTV/Spider as they have no CAN bus).
I agree that it can all seem confusing (it IS confusing, there's no simple way around it). The whole non-OBD2-compliant situation really just means you can't expect to use a generic handheld "code reader"/"scan tool". Instead, you need the specific software FIATECUSCAN (now called MultiECUScan), or AlfaDiag, or AlfaOBD. A Google search works for any of these. At the Multiecuscan - Diagnostics software for Italian cars (Powered by FiatECUScan)
website, you can check in the list of Supported Vehicles to see whether the ECU you want to connect to (e.g. TRW MY97 Airbag) is in red - if so, you'll need to purchase the registered version (50Euro and well worth it) - otherwise, if listed in black, the demo version will do the job.
Also, the Supported Vehicles list shows the adapter wiring (pin number to connect to pin 7) and the wiring of the three Gendan adapters.
Bear in mind that if you ever want to connect to a Spider's hood ECU, only the AlfaOBD software can do that. I think the registered version was another 50 Euro. I don't regret any of my purchases, as I have used them all on 20-odd Alfas and FIATs now. It's really as essential as a timing light and dwell meter used to be
except, they were only for tuning the engine - now you need software to replace a window switch or fix the aircon in modern cars!
