Didn't someone figure out that the cruise power came off the brake light circuit?

I installed mine & am having issues too. Two functions work...accel & cancel. Decel & resume aren't working at all. I'll have to test the switch when I get an hour or two of play time.

I actually tested mine today and it worked! I was amazed that my junkyard pilfering got me cruise for next to nothing (honestly). One thing I did do was change the pics that I posted and put the brake cancel switch on the switch itself. I never tested it the first way as the more I thought about it, how would pushing the brake cancel the cruise with nothing hooked to that switch. I just used alligator clips and kept the end to the plug.

I know accel and decel work on mine, but I never checked resume.

My only issue is that of the smoothness of operation. I sets and works perfectly, but jerks a bit at speed. Is this thanks to having a 4.10 or perhaps should I put or take out some slack on the actuator cable? I'm also thinking that I wound the spring too tight in the actuator when I put it back together...

Ideas?

Can anyone tell me what the wiring going into the cluster looks like? I just have a single cut blue/yellow wire where the plug should be. And if the plug has four pins but one wire, what do the pins do? I plan on making one.

Mine was a very small plug with only the single wire. The plug itself was black, about 3/4" deep and it fit into the green terminal marked 'A'. Do you have the green snap-in receiver for the bottom of the cluster? It's earlier in this post IIRC. You might just be able to tap directly into the cluster itself.

I need to get another switch for mine...the clutch switch and the cruise stalk are both dirty and don't work. I'd HIGHLY recommend testing the clutch and brake circuits with a multimeter before testing on the open road (experience=wisdom in this case)...cruise will fail with the throttle wide open.

I had all this stashed from a parts car I tore down years ago and put it all in when I put my mtech2 wheel and different stalks on. I got all the way to putting the littlepieces on the tb to hold the cable on and dropped it into the area under the intake, where it has never been heard from again.

I used the system from an early 84 eta and it all went in fine. Don,t know if it works though yet since I have to drive 3 hours to hit the nearest junkyard with bmws

Just finished succesful CC instalation. Jakeb instructions has all the information! I used original acutator cable, made screw thread a little bit longer and sawed the end.

It looks like you don't have ABS which may preclude others from doing it that way, but I really like the thought process. Well done.

No, the ABS sits nicely underneath the cruise unit...mine is mounted pretty high with the bracket, it's closer to the hood insulation than the cruise module.

I think you mean the opposite there, yes?

The ABS pump can't be "under" the cruise actuator yet be almost touching the hood insulation...

But I understand what you meant to say. Either way, I'm sure others will appreciate the fact that they can do this more or less as a direct swap from a 6 cyl car.

Finally stickied this damn thing.

Anyone know for sure if the e36 actuator cable that is needed has to be from an m42/m44 or can it be from any of the e36 motors?

Thanks,
Dguy.

Needs to be from a 92' to 94' 318. Actuator cable 65-71-8-357-087 $28.28. Do yourself a favor and replace the accelerator cable at the same time 35-41-1-158-724 $25.95. Throttle body grommets come with the cables and prices were from the dealer with the BMW CCA discount on 10/7/11.

So I just finished this. I used a e34 525's actuator cable, seems to be about the right length for the job.

Comparison here is the e34 cable I used along with an e36 325 cable.

Here's a couple of shots of the clips that hold the cable into the actuator. a couple of screw drivers and it comes out real easy.

Is it me or does the system have a little bit of trouble maintaining a consistent speed?
It varies by about 4-5mph but when it gets to about 5mph above where I wanted it it'll close the throttle completely, the start accelerating a bit.

It's not exactly what I'd call smooth or easy on my engine mounts.

DesktopDave · « **Reply #87 on:** June 14, 2012, 04:46:39 PM »

Mine seems to pulse a few MPH, not more than 1-2mph... Definitely not as smooth as the cruise on my old M20 525i was, but not as bad as the old vac-driven units were.

longtallsally · « **Reply #88 on:** July 15, 2012, 05:57:30 PM »

HI GUYS! Umembuh me?!?

Anyway, to answer thedguy, I think the jerkiness is due to the short gears and type of engine that is in there. A buddy with an E30 M3 verified this a long time ago and mine always worked, but it was never as smooth as in the M20 powered E30s I had...

I thought I just saw a ghost...

Welcome back LTS! Just a drive-by, or did you get the M42 bug again?
