Hey,

I opened my glove box and removed a cover from its bottom. I came upon some relays in a block. Does anyone know what these are for? 93 jeep grand cherokee. Thanks

 

There is a relay center for PCM functions and a automatic headlight module there to.

 

The reason i was asking is because i was installing a stereo today and found one wire that i couldn't
figure out what it was for...so after doing a few different tests i put 12 volts to it and heard a relay clicking in the fuse box. Was curious what the relay was for. Any ideas?

 

What color is the wire, is it part of the radio harness?

(Maybe ZJ's had an option of power antennas, not sure though. My XJ had apower antenna)

 

The wire is green with a red stripe and is in the same bunch as the stereo wires . Someone has ben in there and cut off the original plug but i'm assuming it would have gone into said plug.

 

It's for the power antenna

Here's the wires for that cut off plug, make sure ur speakers a hooked up properly or the speakers will be out of phase(sound like crap)
Constant 12V+ Red/White
Switched 12V+ Red/Gray
Ground Black
Illumination Blue/Red
Dimmer Orange
Antenna Trigger Green/Red
Front Speakers 5 1/4" Doors
Left Front (+) Green
Left Front (-) Brown/Red
Right Front (+) Purple/Yellow
Right Front (-) Blue
Rear Speakers 5 1/4" Rear Doors
Left Rear (+) Brown/Yellow
Left Rear (-) Brown/Light Blue
Right Rear (+) Blue/White
Right Rear (-) Blue/Pink

 

alrighty...thanks for all the info.

 

Do you happen to have the ID's (layout,legend) for the relay centre?

 

I'll take a look for them next time I'm home, working out of province right now so it will be a couple weeks.

 

that would be great, thanks
