Radio Wiring Diagram

Would anyone have the wiring diagram for the radio wiring harness? The previous owner removed the stereo and just cut the harness off when they removed the head unit. Hope they found a use for the harness, knuckleheads! Thanks for any help!

J Spec, thanks a million for the reply! It is greatly appreciated!

No prob, just PM me if you ever need to know anything Car Audio.

Appreciate the offer, I'll be pm'ing you! lol I am trying to figure out what system to go with. I have a new pioneer deck for now. But I am trying to decide on amp(s) subs, mid's etc and I'm not real sure about all that stuff. I'm looking to go maybe mid range as far price goes. I'll pm you later on. Thanks!

Thanks, I have this kind of info for any year of 240, or any car for that matter. I install stereos almost every day. Just ask if you need it.

do you also know the diagram for the 91 240sx's radio?

a little old. start a new thread

do you have a diagram for a 1989 240sx coupe? Radio, or any electrical?

dude. how old is this thread? you passed the first newbie rule in that you used the search function, but you failed the second rule by bringing up a 2 year old thread. other than that, yes i have diagrams but i dont have any way of sharing them with you...go to a dealer and ask, otherwise get the chilton manual.

midnightangel,

They should be the same, as for the other electrical diagrams pick up a 240sx chiltons book at napa or something.
