The wiring diagram I have shows PIN 3 on th ECM as BATTERY and has a red/white wire going to the auto shutdown relay and then out to the fuel pump relay. Having chopped out the auto shut down, it can go straight to the fuel pump relay and then on to a fused power source - in other words, in reverse, the battery hot comes in from a fused source into the fuel pump relay and out to the pcm. So that takes care of pcm power.
If I don't have to run the alternator through the pcm, and I can hook it up as it used to be, then I need to 'hide' the funky wires that are intended to connect to the alternator - they are green (from PCM) and green/orange. BUT that means two things I think....
1. There are three connectors for the newer non voltage regulated alternator. B+ (BAT), a green and a green with orange stripe. I believe the green goes to PIN 20, marked 'ALTERNATOR IND'.
2. I believe the green with orange is sent 'from' the pcm and goes to all the injectors and alternator to decide how long to inject for in an over/undercharged situation and is on PIN 67 and is marked "ASD BATTERY SENS". It is also connected to one of the field sensing points on the alternator. which in turn seems to go to the Coil as well!
So I have read that putting a resistor across the two field wires tricks the computer into thinking the alternator is there.
I know my alternator will work as it is set up but if I simply do not connect the green or green orange to the wiring, other than throwing codes, will it make a difference?
I have the VSS hooked up, all other cam / crank / map / o2 (no exhaust to put it in but i have it) / tps / air intake connected.
Dare I try to start?
