Cruise control question (87 325ic) - BMW Forum

luckycat · 12-21-2005, 08:21 AM

HI,
Just bought a lovely 87 325 for my daughter is pristine condition. It has almost all the options my 87 325ic does, except the cruise control, which she would like to have if possible.
Question is, if I buy all the components from scrap yard to install in her car, will all the factory harnesses be in place, so that it's a "plug and play" deal, or am I asking for a headache. I am a electronics guy, so the electronics don't scare me. But I sure dont want to pull the dash apart if I don't have too!!!

Thanks!

Jim

As far as I know, you should be able to just replace the control, and run your wiring then go. I'm not certain though, so don't hold me to it.

I'm an electrician as well, but I have to admit, that kind of mod scares me.
... and honestly, I have no idea whether or not it's plug and play.
p.s. In my opinion, the cruise control on E30's sucks. Mine does, anyways.

I'm surprised that yours is not right Idsbeaker, I love mine, it's easy to use and accurate. Maybe you have a problem. Thanks for your advice though.
In taking delivery of the 325, one of the few problems I've found is a burned out dash bulb. So when I pull the cluster, I check for the cruise wiring before I make a decision.

Thanks again
Jim

Is your daughter's car a manual or auto?

Her 325 is an Automatic. My 325ic (pic) is a 5-speed with cruise.

It's not that bad of a job once you have the dash harness. Check and see if you have the connector for the cruse module above the glove box next to the ECU, if you are lucky, you may allready have the dash harness there. There are no vacume lines, there should be a rubber or plastic plug that covers the cruise switch hole. If I can remember correctly it mostly just plugs in. The 89 and newer cruise system is better.

Good luck.

it"s all plug and play, fairly simple to retrofit.

you can install C/C module somewhere near gauge cluster so there"s no need to run harness all the way across dashboard.

there's 2 types of actuators and they are define by where the radiator's expansion tank is located., if in passanger side then you'll need an actuator that bolts onto inner fender wall, if tank is in driverside then you'll need one that attaches to same spot but as AFM.

also get the jumper to bypass cluch pedal switch.
