a couple questions

[jakeb]

Does anyone have a drawing of the vacume lines under the intake. I have a few I am not sure where they go. The PO of my engine pulled the manifold off so I need to figure out where everything goes.

Also there are 3 2 pin plugs under the manifold. Does anyone have a list of wire colors and where they all go?

There is one coming off the harness that plugs into the HFM not sure what that is for.

I have been searching but have not found what I am looking for.

Engine? OBD1? OBD2?

e34 m50

[jakeb]

I found this list....are these correct?

oil pressure sensor BRN/GRN or BRN/GRY
front coolant temperature sensor (ECU) BRN/RED BRN
rear coolant temperature sensor (Gauge Sensor) BRN/YEL BRN/VIO
cam position sensor YEL RED/WHT BRN/ORG
VANOS solenoid RED/WHT GRN/BLU
throttle position sensor (TPS) BRN BRN/BLK RED/YEL
intake air temperature (IAT) sensor BRN GRY
idle control valve (ICV) WHT/YEL RED/WHT WHT/GRN
crank position sensor YEL BLK NCA
Evaporative emissions valve BRN RED/WHT


One connection I am finding is BLU/YEL and GREN/WHT

Is there a pinout for an ecu somewhere. Does anyone have a ETM for a 93 e34 m50 they could send me...?

You can find it at http://www.wedophones.com/BMWManualsLead.htm

There is no pinout for the DME located in the ETM, but you can pretty much find the wire colors on the Fuel Injection section of the ETM.

That list probably is the pinout that I created for the E36 325i harness when I had to wire up my engine.

Freddy, there is a pin out for the DME in the ETM, just not for the x20. It doesn't tell you wire colors, just functions.

[FredK]

Well I'll be! There IS a pin out for the DME (X6000)! :mrgreen:

[jakeb]

Well I probed the DME connection to find out what this BLU/YEL and GREN/WHT connector is and there is no connection between it at the DME. Maybe it is something that goes to the x20. I will check there tomorrow.

Any idea what this connection is for?

Also I am still looking for a routing of all the vacuum lines.

[Mike B.]

Blue/Yellow may be the reverse switch on the transmission.

[jakeb]

checked the x20 and yes it is the backup light connection
