The small blue connector in the pic below...



The larger blue connector has a Heated Rear Window switch attached, what's the smaller blue connector for though? foglight? instrument dimmer?

Car is a 92' Eunos Roadster 1.6 manual.

Yeah, a JDM car, in the UK, and I'm asking for advice on a US forum

 

Could be power mirrors, foglights.

Have a great day,

If it's you instrument dimmer you won't have dash lights AT ALL when it's not plugged in.

 

so I guess that's the instrument dimmer idea out the window then....

My rear fog light is located in the rear light cluster, with a non-standard switch on the steering cowl.... it works, and looks better than the stuck-on foglights I often see on imports over here.

maybe it's for front fogs?

 

Cruise control?

 

I can check mine during lunch...I thought it had more than 3 wired terminals, but I guess it's really just a switch since most of the cruise controls are on the stalk.

 

I would guess fog lights, since it has 3 wires. At least I assume the factory fog light switch has illumination.

 

It would be helpful if we knew what the wire colors were.

It sure looks like the dimmer switch. Three wires in a keyed six-position housing. Wire colors would be Black (gnd), Red/Blue (power in from TNS relay) and Red (switched ground for lamps).

It's not fog lights or cruise control. Fog lights would be four wires in a non-keyed six position plug, cruise uses a similar plug to dimmer, but with six wires.

 

Thanks for the replies.

I just checked the wire colours, there is a Red, a (thinner guage) Black, and a Red with black stripe.
