time to pull out teh test light.

the positive one will be the one thats hot all the time,, and ACC is the one thats only hot when the key is on or at ACC position (key back)

[marquisman]

Why didn't I think of that? :coocoo:


WIRES:

Green: Constant power
Yellow (2 wires in one slot): Acc
Orange: Acc
Black: ?
Blue: ?

1. Which "Acc" wire should I hook into? I'm thinking I'll use the Orange one.

2. What is the red wire for in the second pic? It was on the bolt in back of the stereo.

3. Where is a good place to put the new stereos' Ground Wire?

4. What is the big yellow plug down the wire for? (first pic)

5. How does the headlight switch knob come off?

is it possible to disable the factory amp without buying the bypass cable?

[85crownHPP]

OOO!!! that big yellow thing is an auxillary connection!!! use it! you said yellow was power with key on right? the reason there are two of them at the harness, is becuase one of them goes back to the yellow plug, and is meant to be tapped!
get yourself a crimp banana plug and stick it in! (when you need to power something, like a relay to turn on a CB, or foglights!)

as for your other wires... do I see three harnesses for your factory radio?? you must have premium sound... how does the wiring harness you bought fit these???
there are two kinds, a use-the-amp and an amp bypass harness... do you know what you have?

and do you need to use the install kit or do you have those tabs like jackup460's???

oh and back behind the ashtray, on the dash frame near the firewall, there is a handy strip of ground tabs there ready to use a female spade connector... at least I hope you have them. I do!

[85crownHPP]

is it possible to disable the factory amp without buying the bypass cable?

yes, by hard wiring it.

[Grand Marquis GT]

The headlight switch knob....

I belive you pull it out to turn it on...reach up behind there and theres a little tiny spring loaded button on there...

push that in and hold it...push the lights back in to turn off, and pull right out. You will prob have to fiddle with it, its been awhile

that is a premium sound harness. what a fucking pita. i've never seen a use-the-amp harness for teh older boxes, i've only seen the amp bypass harnesses, i have seen for the 90-91's a use-the-amp harness, because i have one

[Paul_]

you'll honestly save ypurself a crapload of troule just by running new speaker wire. it'll sound better too. i'm assuming you have door speakers??

[monterey1962]

Yes, the car has Premium Sound, but I am running all new wiring.

I do not need an instal kit. The factory clip and side mounts work fine.

Yes, I have door speakers.

New stereo is in and functional. Sounds much better than before and it's great having a CD player on board.
