Thanks guys for the great detective work! I guess if we couldn't fabricate amounting bracket we could go to the stealership:eek:
The 325 CC unit should still work if need be, right?
I'll have do do some looking for an e36 m42 CC unit.
This is good stuff here guys.
Thanks,Dan.

Great detective work here guys! I'm watching this one like a hawk.
Question: Based on what we know at this point, will there be much fabrication to this, or will it simply be a mater of finding the correct mix of E36 and E30 parts, then hooking them up?

At this point it looks like a mix of E36 and E30 parts... but we need to verify the electronics are E30.

Sending you pics now...your assumption seems to be correct for the mix of e36 mechanicals under the hood and e30 controls in the cabin.

BTW - The throttle bracket is the same. The cable is just routed the opposite way with the cruise setup. PN 13541727147 applies to e36 and e30 cars.

The part we need to see, the cruise computer is behind the glove compartment...

You mentioned that you were ripping it all out of your car and potentially putting it in your other E30? When you do that, we can get a good look at the other components - the cruise computer, the wiring harness, and the clutch/brake switch.

Awesome pics e9nine, great help for this thread.
Thanks, Dan.

shamefully stolen from http://www.e30.de

Oh and tempomat i'm fairly sure means cruise control in german...

Tempomat fitting instruction

The Tempomat installation becomes following into a 318i M40 Touring transmission (no Tempomat preparation). The VDO is blocked compactly speed act.

1. Assembly of the actuator (inclusive control electronics)
� The 3 point base plate somewhat modify and onto the front mounting plate of the air cleaner with screw
� The actuator is to look with cable assembly toward tail
� Cable assembly shorten and in light elbow to the gas modulator at the engine lead
� Cable assembly by the second hole pull
� The course to the original course fasten
� The coat of the cable assembly at the original coat with provided clamp fix. Note: not too firmly
screw on, otherwise one wedges the gas courses
� Cable assembly now with cable straps fix. Tap: if one the cable assembly before the actuator at one
immovable point fixed, no vibration to the actuator transferred => longer lifetime, improves
Functionality

2. Wiring harness shift
� Upper floor space lining on the driver's side remove (possibly equal lower steering column cover
decreases, needs one later still)
� In the floor space direction front is above on the left of a rubber plate from which one before-perforated holes
to take out can come over into the engine compartment. Take as small a hole as possible and
cut out (possibly one does not have to seal it later again somewhat thereby it wet clean-come,
that do not have I yet tested)
� Wiring harness at the controller stick on and only times isolate with provided spaghetti tubing
� Now wiring harness by the before opened hole into the floor space lead. The hole finds it underneath of the
Fuse box. Who small hands has may come. I not => considerable Gepfrimel. Tap: I
to me such a small tube from the aquarium need took (pale pipe for peas) and there one
Cord through led. At the other end made and then one knows a loop there the 5 pins of
Guidance switches get jammed. Subsequently, the pins with our extension by the hole press (that
Rubber stretches rather, but nevertheless watch out that nix tears. And tata we are in the floor space
� Now the wiring harness on the desired length pull tight
� Wiring harness in the engine compartment fasten

3. Tachogeber signal measure
� Combination instrument (Tacho tachometer unit) remove
� Now divide (some screws on the back)
� Tacho develop (once again 4 screws on the back)
� To the Tachoeinheit is there a pin 31b. There the Tachogeber signal is measured. I have to the pin
a cable soldered and this by a small hole on the back implemented (lustre terminal to)

4. Clutch switches install
� In the floor space direction front is left over the clutch pedal a short Metalleiste 8x3cm. There become
a few things grounded
� The groundings of the lower screw unscrew and to the upper screw to
� Now the provided flat iron is installed onto that the clutch switch to shorten in such a way and bend that
to be installed there can
� Clutch switches drauf and still in such a way bend that also really everything fit
� Function examine: with clutch in resting position the switch must be pressed

5. Connect from clutch and brake switches
� You look there best into the guidance
� Short: a cable (brown goes into the Bramsschalter purely), a second short goes from the BS to the KS and of
KS goes third (lila) toward controller.
� However with + and - must kucken you once again

6. Steering column switches install
� Lower steering column cover off (there the steering wheel must also also off)
� There lever a Vorpr�gung on the inside of the lower is left under+behind half from the windshield wiper
Steering column cover.
� Hole bore
� Levers accomplish
� Levers bend in such a way that it sits correctly
� Bolting on
� Lining again to

7. Connection of all cables and switches to the wiring harness
� Well, no problem should be. Is as paint from numbers (see guidance)

8. Power connection for controller
� There gibts a cable measures the river for the controller at the radio that supplies 12 V when more switched on
Ignition that is the correct

I got an entire e30 cruise setup and I have a e36 318 acuator on its way to me. I should have it next week sometime. Does anyone have a good wiring diagram for the cruise system on a e30. I will report back when i get the e36 acuator if it has the same connector as the e30 harness. I want to know all the wires parts of this and where everything plugs in before I pull apart my dash. (also plan to install the OBC at the same time)

I plan to document the install when I do it.

A Couple questions....if i turn the key with the airbag out with I assume the SRS light will stay on. Will it go out once I hook everything back up?
Next...is the speed sensor in the diff? Would be nice to jack the rear up and test the cruise before i am on the road.

jakeb you are the man!

Are you taking pics of the install?

I don't know about the SRS light but maybe someone else will post on it.

The speed sensor is in the diff.

Check the Haynes manual thread here, maybe a wiring diagram is in there. I don't know if realoem.com has wiring info.

Good luck and keep us posted you pioneer you.
Dan.
