Wiring uv7i I bought a uv7i deck off ebay and it didn't come with the 16 pin power/speaker plug. Ifound a plug that fits but it comes from a different manufacturer, I would like to know the color sequience on the factory plug so I don't fry the deck . Also reading some of the problems on this site, will this deck work without a remote??

Make sure that the speaker wiring is correctly connected. Please see the instruction manual that would have come with the Pioneer deck for correct wiring instructions first. Check that first and let me know..

There may be many different power supplies that will work for your speaker system, but they must comply with the following:
1. The output voltage of the power supply should be correct as what the speaker system requires. (seems like 12 V in your case)
2. The specified maximum current output of the power supply should always be a higher value than the Amperage spec of the speaker system.
3. The output wires or pins of the plug on the power supply should correspond to the (+) and (-) on the power input of the speaker system.

A multimeter will come in handy to determine a power supply's output voltage and polarity.

If it is the basic radio then here are the wiring pins for it:

RT FT Speaker - Pin 18
RT FT Speaker + Pin 1
LFT FT Speaker + Pin 16
LFT RR Speaker - Pin 17

Power and Neg pins are Battery Pin 10, Ground Pin 11

Ignition Pin 12

Another Power & Neg pins are Battery Pin 19, Battery Pin 20

These are the Pin Connectors for the stereo.

just make one dude its easy its the ending of wires of any harness just pull one out of a different wireing harness and push in that harness and wala yup that simple get back at me theses harnesses everywhere old stereo or buy one cheap on from walmart stereo dept.

hook the RCAs into the preamp outputs

you have a factory amp, you need a aftermarket deck harness, it will plug into your factory deck wiring and then plug into your after market deck, your speakers will then work

facing the back of the 7940 the top left corner is pin 16 the top right corner is pin 9. The bottom left is pin 8 and the bottom right is pin 1. Only a few of the 16 pins are used due to this unit only having pre-outs, no internal amplifier on this unit. Pin 1 red (ignition), Pin 2 pink/black (interrupt), Pin 3 orange (Illumination), Pin 8 black (ground), Pin 9 blue (power antenna), Pin 10 blue/white (remote turn on), Pin 16 yellow (battery).

my first suspect would be the harness adapter, if your sound was working ok before fitting the the new decks:take the part number of the adapter and check it again even if you have to check it on line with the manafactures to see it is compatable with your new decks/and your car chassis number.adrian
