What is this one for...
 

Hey guys, I was going to try the OEM cruise control install on my 90. So I started looking to see if it had the wiring harness behind the dash and in the engine compartment. Going from the pictures off of M.net I have neither. But it does have this one, its directly to the left of the steering column next to the the dimming switch. It has a blank cover over it. Any ideas what its for?

Thanks,
Ryan

was going to say power mirrors....but i dont think 1.6's had that option. could have also been rear defroster...but again, the 1.6's didnt have it...

Wrong and wrong. Good try though.

Could be for DRL module

Edit: No, sorry, Fog Light Option

comprehension fail is me.

if that is there, would there be a wiring harness in the front bumper or radiator cowl for it?

Foglights.

I think that the blue connector to the left of the one you've got hanging out is the cruise switch.

Here's the complete system diagram for cruise control:

Note that if the vehicle was not originally equipped with cruise control, some of these wires may be missing from the harness. For instance, I know that in 1.6 vehicles with neither an automatic transmission nor factory cruise, the G/R wire (at position P here) is missing between common connector X-17 and the instrument panel connector. Annoyingly, the actual VSS itself is present, there's just no wire going to it.

Also, I think fooger03 may be half-right on the rear defogger. I know that the later 1.6 cars were pre-wired for it, but I don't think that the '90-'91 cars were.

the blue connector to the left of it is the dimmer switch. I had it pulled out and unplugged so I could change the light in it. I was hoping the I would be lucky and have some of the cruise control stuff pre-wired, but its not looking that way. And looking at that wiring diagram right now looks like a bunch of scribbles. I will have to look at it again tomorrow, thank you for posting that though. I love cruise control and would love to go OEM but if I have to go aftermarket thats fine too

i have a full oem cruise setup i pulled off my car whats it worth to ya?

well I was offered $125 by another board member for his complete setup. My only concern is I was reading and it people have said if you dont have to wiring looms present to go aftermarket and save yourself the headache. So I am not entirely sure what I want to do...
