how-to installing AP900 cruise control to Stagea M35?

[germanstagea]

hi there,

i bought a AP900Ci which i got cheaper from a private seller. i also ordered a 350Z T-wire to make it a plug an play kit but once reading the instructions i´m a bid confused.

what i want is, to use the OEM steering wheel buttons (allready got them used from usa). the instructions for using OEM buttons show a 3-wire and a 4-wire diagram. the problem is, that the Stagea OEM buttons does have just 2-wire.

i don´t want to use the liteon control stack. i want to use just the steering wheel buttons. any idea?

i know this thread: https://www.sau.com.au/forums/topic/384164-fs-cruise-controls-for-m35-v35-diy-install/page/6/#comments

 

and from what i read it seams to be possible to use just the steering wheel buttons for "main functions". did anyone installed the AP900 by himself or had the instructions from Commsman?

seams that i found the solution....

the instructions say, that there is a learning mode for "standard Command Module".

i will going to try this on weekend and will let you know if i got it working.

did anyone have an idea where to get speed signal from? as i don´t have a USB-data cable to reprogram my AP900Ci i would like to wire it in manually may without can-bus. only signal i wasn´t able to find is speed, as ECU don´t have speed signal wire (it gets it from CAN-BUS).

i read somewhere that the atessa ecu have a speed signal and that there should be a 4-pin plug with speed signal close to the OBD-plug.

 

if anyone have an information which helps, please let me know. big thanks!!!

did anyone know the wiring of the abs controll unit and where its located? couldn´t find anything on google.

maybe it would be an option to get the signal from one abs sensor.

 

i read that g35 does have speed signal on radio wiring, no idea if its 100% the same. will have a look tomorrow on my radio wiring.

found a pinout of the abs / ets unit, but didn´t found the location of it. even with nissan fast i wasn´t able to locate it.

but i had another idea today....

BCM should be the unit which converting the speed signal into can-bus signal, isn´t it? BCM is located in drivers side foot room where the fusebox is located. maybe i could get the speed signal from there!?

i found the japanese workshop manual for M35Stagea yesterday and translated all sites to english.

looks like i found a useable speed signal.

i have fully wired the AP900 today. will going to calibrate and test it tomorrow. if it work with this signal i write a short tutorial how to wire the cruise contoller if you don´t want to use can-bus.

the information with the non-canbus speed signal could be useful for other things, isn´t it!?
