Does the 4 wire Blue Box leave codes

I would verify your statement about green being a ground w/ Blue Chip.



I believe on mine, green went to the map sensor harness adaptor. The long Red went to the pump wire (closest to the motor), the other long one (black?) went to the main pump harness (brown in the harness) which I was told is the same as ground.



Also, the shorter red went to the fuse box for power (engine fuse - maybe #9). Also a shorter black which is negative (ground).



Again, verify this first.
 
Hey thats great. I was concerned that the color codes may have changed.



If you want a quicker throttle response, after you get it hooked up & working, just disconnect the green wire from the MAP harness (maybe wrap it w/ some tape so it doesnt short out anything).



That disables the boost delay, and makes it run alot snappier!



You just have to be more aware of smoke, as itll make plenty before the boost comes up. Thats the way I ended up running mine. Good luck & beware of frying drivetrain components!
