what is this for?

[maddog]

i decided to try and start Survivor today and after i got her started i went around to the front of her while the hood was up and saw smoke coming from this switch i quickly unplugged it and she stayed running i then shut her off and then tried starting her again and she immediately fired right up. now i know it is some sort of switch but as to what it's for i have no clue.here are some pics.

It's a simple BOSCH relay.  For lights, ACC, etc......

[eagleman]

I believe thats a light relay!Do you have fog lights?

[maddog]

i have factory driving lights.

[eagleman]

By factory driving lights I'm assuming you have the bumper mounted fog lights or what some folks refer to as driving lights.Anyway that relay appears to be the relay for those lights and is mounted on the pass side inner fender. Mine is real close to the starter sol. but have seen some mounted futher back and even on the pass side fire wall.

Here you go.  This is as simple as it breaks down.

I ise these on all my lights/relays.  Get a brighter bulb/etc

Depending on the location, some Eagles used a pair of those solenoids mounted to the inner wheel well just behind the passenger side shock tower and above where the cruise control sits.  They were used to control the various smog and emissions crap on the 4.2's.
