I've been installing a Pyle PLTSD7BT on a 94 lexus SC300. But it just won't turn on. Ive been using this diagram because its the only one that matches my stock system and its color coded as well:

I'm hoping I haven't messed up any fuses. I figured my problem is probably with the memory battery or ACC wires.

Currently I have it wired like this ((not working)):

Yellow (battery anode +12v): +B plug
Red (12v ACC/Right+): Acc plug
Grey (Amplifier power control line): None
Black (ground): wrapped around metal screw underneath the shifter
Blue (power antenna): P/Green and P/BLue wires
Pink (Braking line): None


I saw somewhere that someone had a 12v amp wire hooked in the memory battery place and that there is a wire for the braking line under the shifter. I don't know if not having the brake wire. What could be keeping the headunit from turning on? Could someone take a look at that diagram and tell me what I am doing wrong and what I should have hooked where? I just want it to turn on!

A HUGE thanks in advance
((sorry for making this so long. Just wanted to make sure I covered everything))

If you want to verify the unit functions, consider getting your power directly from the battery (or any 12V battery) as well as ground, and see if she'll even turn on. Once you verified that, you can move forward by checking ground against battery direct, and normal wiring for power vs. the ground you have. One's likely not right.

Tell me you are using a harness to plug into the car and not hacking the stock harness?? If so, all the wire colors you need should be on the harness...

Use a DMM to make sure your Acc wire is hot when the iginition is on. Also, check your resistence on your ground. Sounds like that spot may not be good enough. Like the above poster suggested, run wires straight to the battery for both and try again.

How do I get power from the battery directly?

NO harness...and i don't have a DMM

Run 14 guage wire directly to the positive battery post and the other end to your power wire on your head unit.

I got it all working. Turned out to be burnt radio fuses. but now The rear two speakers aren't working. Any ideas why? I have it wired properly.

also, How can i be sure the factory amp is working? and does anyone know how to wire the factory sub to be used with the RCA sub output on the stereo?

PYLE...of crap :)
My first real sub setup was a Pyle.
Might have touched wires during install. Or crossed circuits during manufacture. :)
Stupid Chinese. :)

It's 100% a total crap shoot then.. Who knows what wires you may have shorted during the install..

glad you got it running, but without a harness, it's a hack job at best..
