yeah thanks for the link. i had a play last night and from what i can see pin 39 does nothing when vats is off. prnd sw i wired in series with start relay and it cranks over no problems. have a few little things to do before i can fire it so will keep on it and see if i have spark and injection. che...

hey probably a dumb question but i have made a standalone harness and getting to the point of kicking it over. i have the p59 pcm and blue pin 39 is "start enable relay" how does this wire in when used with the PRND sw when no bcm is used? or is it even active with vats removed? hope this ...

The Generator Field Duty Cycle signal is technically not needed. It's just a check the PCM can do on the alt. All you need is to have the single wire "turn on/off" signal. I assume this is the same for your setup. I have used both in the past and also just the single wire. Works either wa...

i think i may have found it. can anyone confirm. i move pin 52 to pin 75. so pins 15 and pin 75 on first picture

normal pinout as per loom

hey people. my build has a pcm regulated altinator (05 vz holden ls1) im changing the os to suit 3bar dbc and SD and before i get to it wanted to check the outputs will still work. its pin 15 and 52 on my pcm but the standalone harness i have does not have 52 wired. if i run the wire will it still w...

yeah bugger.
i have a p59 from a awd ls1 (holden Adventra) i wanted to make it dbc it has the iac chip. i wanted to keep the basic config but i have to change it to dbc, 3 bar and remove vats.

keep looking i guess
cheers

its just a bin im trying to put together for my 56 chev ls. this an 12587811 but being 1mb file only the 603 osid i could find for that?
