Radio harness no power - need help


Recommended Posts

I am currently having an issue with no power in the stereo harness. In the plug shown below there is no power in both the constant 12v (yellow wire) and ignition 12v (red wire).

I also found the indicated connector in the second photo identical to the one for the stereo. This is located on the drivers side footwell. Checked with meter for continuity and found that both connectors are on the same harness as confirmed continuity. Can anyone confirm if this needs to be connected to anything? Have found no loose plugs nearby. Would appreciate if anyone can post photos.

If I remember rightly the yellow black red white plug is for rears speakers ( there is normally the plug on the rear right behind trim worth a look unless some one has tapped it in to the foot well as the black electrical tape isn’t standard ) and the other plug next to it is for front speaker , 12v , 12+ . Ground . 👍🏼

Taken from 96/97 European EP91 Toyota Electrical Manual.

Speakers:

RR+ = Red, RR- = white, RL+ = Black, RL- = Yellow.

FR+ = Light green, FR- = blue, FL+ = Pink, FL- = Violet.

Power:

Constant 12v = blue with yellow stripe, acc 12v = grey, gnd = brown.

Constant 12v from 10A Dome fuse (engine bay fuse box), acc 12v from 15A Rad & cig fuse (fuse box under steering column).

*Can't find reference to the dark green wire though?

Plug in the drivers footwell can be extended to the rear for parcel shelf speakers.

From factory a new loom was added to power up rear speakers and this was always unused.
