sonofsam 5 Posted September 28, 2006 pin1=bmf4j battery livepin2 = nil pin3 = 820 diag plug (match with number on wire to ecu) pin4 = 821 diag plug (match with number on wire to ecu. sometimes joined with pin3 on keypad a short way up the loom) pin5 = 1031 live while cranking, probably ignore for now pin6 = nil pin7 = nil pin8 = 824 (match with number on wire to ecu or ignore for now) pin9 = 6219 central locking, state changes when locked, ignore for now, may prevent rearming if left off pin10 = nil pin11 = 3050 (not sure, probably central locking. ignore for now) pin12 = nil pin13 =c02 ignition live pin14 = 822 output to main relay coil. live when immob deactivated (max 300ma, recommend use bulb to limit current while testing) pin15 = m8200 mass (earth) Courtesy of Fuqa.

sonofsam 5 Posted September 28, 2006 I'd keep the keypad personally, wish I had the chance to, but my loom was so butchered i had no chance! Good bit of extra security in my mind:) Scrapping your turbo already John? Share this post Link to post Share on other sites

inferno 1 Posted September 28, 2006 there are a million different stories, all i know is that mine would not work unless i had my ecu unlocked. unlocked being removing te keypad when engine is running imo the keypad is a good idea, u can always delock it if it bores you after a while!
