4
COLOR & PURPOSE OF (HARNESS SIDE) WIRES:
pink-black “A”, goes to ECM/SOL fuse
(connects to brake switch)
(junction, connects with many other things)
gray “B”, goes to ECM (“A4” exhaust gas recirculation (EGR) control)
(junction connects with ALDL “H”)
(junction connects with other things)
brown “C”, goes to ECM (“D9” diagnostic input)
black “D”, goes to (junction) to ground
(junction connects with other things)
.
OTHER NOTES:
[SEE EGR Valve]
[SEE vacuum routing here]
called “electronic vacuum regulator valve (EVRV)” on diagrams.
valve (circuit) is closed with vacuum.
The hose that is closest to the drivers valve cover should be the one going to the EGR Valve.
The other hose goes thru several check valves, then to vacuum block on top of engine.
