Cruise Control

[kimokalihi]

I have a an automatic 90 Legacy Wagon AWD and I realized there's a blank spot where the cruise control button goes. So I went to the junkyard and got the switch and the controls that goes in the steering wheel and hoped that it would work. It does not, of course.

 

I tried looking in the haynes book but it doesn't tell me what I need to get to have cruise control in a car that never had it before.

 

I know I'm missing some stuff. I've been told maybe some sort of ECU and vacuum line and brake cable attachment of some sort?

 

Is this task hopeless?

 

I know a pretty decent amount about cars, just nothing about cruise control since this is the first vehicle I've ever had that actually had that option.

 

Thanks. I searched for this but didn't find much. At least not enough information to get the job done.

umm...did you get the cruise control cable, throttle body, and actuator? those are sorta important. beyond that, i dunno anything about the electronics (i hate that stuff)

 

edit: nevermind, other thread found

Nope, none of that. I had no idea at the time that it was anything more than electronics and the switches.

 

I guess if it was all controlled purely from electronics, they'd put it on all the models.

Hey I've got a question my cruise control doesn't work, I think it might be the stoplight switch..

 

Any idea..

worn or out of adjustment brake light switchs are quite common cruise killers.

Yah you'd have to look at the salvage car and get all the components. Look at the throttle body and you'll see two cables - one goes to the gas pedal, the other goes to the cruise control unit. You need that cruise control unit and any wiring and vacuum lines, etc. that come off of it. Hopefully your car already has the connector for the thing.
