Apexi S-afc Wiring Rb20det

[Quigga]

Hey guys before i get the flamings saying USE THE SEARCH BUTTON i have! here and throughout the net to no avail, IT WONT TURN ON

Before u ask i used vehicle specific diagram 14a nissan - skyline - rb20det

first of all im leaning towards the fact my safc is 2nd had and may be broken due to it not turning on but i saw somthing in the guide that made me think otherwise (skylines being an ecception but i think it reffers to gtr rb26dett)

anyway ive wired to wat it should be BUT the yellow and white (afm input/output) which isnt made in the pinout it just shows the afm cable so (help plz on what it needs to be wired to)

even though they are not wired the power and ground's are and it wont turn on when i put the ignition on?

there are some other wires that are not doin anything either which i was assuming is normal (for rsm and itc maybe?)

please help

THANKS QUIGGA

now feel free to correct me if i am wrong, but if you take it out and just put the power wires onto the terminals of the battery then that should tell you whether the unit will turn on ot not.

it was the first thing i tried but yet nothing hence posting here

can you put up the wiring diagram that you used or a link to where you got it from?? i haven't put one of these in before but have done a few piggyback computers, i know some of these units have two grounds and will not turn on without both grounds being grounded,

N4-a (i haven't wired mine up yet but will do so in the next month or two probably)

read page 3 properly

is the unit grounded like the manual say with the brown wire on the ecu side and the black wire about 1cm up from that?

with the AFM wire you will need to cut the AFM wire on the ecu and hook up to the wire coming from the AFM to the white wire and then the yellow wire back to the ecu.

have now changed afm to the way u stated cheers green_13

Perhaps the unit is dead? If it's wired up correctly and it still doesn't work... then you run it from 12v and it STILL doesn't work... maybe?
