93 oem radio help...
 

i installed the 3 components needed to have a radio in my 93 k1500 reg cab and there is a 1 white wire underneith the white wire coming off the harness from the radio face harness going into the main brain and im not sure of where it connects to or even if my truck had the optional graphic equalizer or not in the first place, my guess it has something to do with changing the frequencies on the eq. please help me figure out how to get my eq to work

Would a wiring diagram help?
Attachment 780494

It doesn't show the extra wire but the main wire looks to be a data wire...and the extra wire is also the same white color but a single connector at the end

does your radio and everything work as it should? if yes and the mystery wire is coming from the radio itself, its a remote wire. it's essentially a switch that turns on an amp if you were running one.

Well the one wire does come from the harness from the radio plug that connects to the brain by the gas petal and just went into the main harness behind the dash of the truck it came out of in the bone yard and the radio functions normal but the eq in the cassette player won't change frequencies to change bass, mids, and highs now that you are saying it is a remote wire does make sense but idk why it would need a remote wire unless the equalizer is a amplifier as well

does the EQ turn on? if so its not a remote wire for the EQ. all a remote does is send a small current to "switch" an amp on. I'm gonna bet bad EQ but at this point without looking at it myself I'm drawing a blank.

The eq does turn on but only the scale showsnot the bars for adjustment I'm thinking about putting power to the wire and seeing if it works
