Its sorta simple really ive never had this problem in any civic ive owned but i got a 1989 honda civic hatchback DX and ive attempted to install my radio but the previous owner had cut the wires so i did it manualy and as far as the radio it works but when i shut the car off it losses memory so ive got the ACC wire hooked up and the only way the radio will work is if i hook the 2 ACC wires and the batt. Mem wire up togather ive used a test light and can not find no live wire to support memory for when i shut the car off im at a complete loss and i can not find a wiring Diag online can anyone help? you can post a reply or email me at OrlandoSuxx@aol.com thank you!!

 

here are wiring pinouts - i have diagram if you need it

 

well i have the pin outs my main problem is what wire is the Batt.Mem , well ill try this again i have a pioneer iver hooked all the wires up top that diag u showed but my problem is that i lose my memory when i shut the car off and the only way i can get the radio to work is if i hook up the Batt.Memory wire from the radio to the ACC wire to the car so thats a total of 2 wires that i half to run to the ACC wire from the car inorder to get the radio to work but i still loses memory cause its not a constant power source, i hope this helps more

 

i just studyed that diag u showed me but the problem is it doesnt match upp 100% cause the Main stero power supply isnt whte/green its yellow/red well its the only live wire when the car is on

 

Ok also let me just add this there is NO Orig. wire harness wired into the car just spliced wires

 

Look for a white w/blue stripe wire that should be always hot.
(I went throught the same thing with my CRX; some fool cut the connector for the radio off the wiring harness.)

 

Without the original wiring harness, try this:
-turn the ignition key to off
-connect the ground clamp of your circuit power tester to ground
-test each fuse under the steering wheel (looking for one that remains hot with the car completely off)

I think, the fuse (circuit) that supplies the ECU's memory is always hot.

 

when the car is off there is no hot wire at all and the radio fuse under the dash is fine

 

thjis sounds good to me.....maybe it is tucked...or cut really short.

also....it is really hard to read your posts. i almost fainted from not breathing since you dont have any punctuation.

 

No i found the w/blue wire. and it is not hot!!!!!!!!
