Pc2 Or Pc3

[brice1ie]

hi there,

Just got a new double din headunit... just finished making it all up.. but when i connected it... ZERO... nothing happened!! Have tried everything and still no joy... The harness they gave me is a PC2-93-4

It says Lexus amp harness..... 98-03

Is it the wrong harness, and if so does anyone have athe layout to de-pin it and repin to make it work??

Thanks.

Did you get one of the amp harnesses off eBay or just a standard Toyota harness? The Toyota ones don't work for IS models with an amp, you need to get a custom one off eBay :)

No i bought an autoleads version.... but on a further inspection just realised... it doesnt have an ACC line in the harness.. If i swap the cables and put the ACC on the MEMORY wire.. works without a problem... but the brains at pioneer didnt put an OF switch on the headunit... which detroys that idea... how crazy is that.... anyone know what wire on the cars harness is the ACC so i can add a wire to the connector??

Also what the hell is a vehicle injection computer and where is it??

Thanks.

OK.... really need help??

Is there no ACC wire in the connector from the amp that you join to the bypass harness???

If there isnt has anyone any idea where is easy access to connect the radio´s ACC wire

Thanks...
