Finally installed it, I used PC2-105-4 wiring harness adaptor and all speakers work well. Most difficult thing was trying to unplug the cable off the amplifier (crowded area), other than that, everything else was pretty straight forward.
I was told by this seller that I need this harness wiring- PC2-105-4 but I found this: http://www.ebay.co.uk/itm/Lexus-IS200-Amplifier-Bypass-Wiring-Harness-PC2-105-4-/400338695184?pt=UK_In_Car_Technology&hash=item5d360bb410 which is the same harness wiring from the same seller but 5 pounds cheaper... :eerrrmm: ??
I'm getting this one: http://www.ebay.co.uk/itm/270643336934?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
They are both the same but it's slightly cheaper... XD
I'm trying to replace the OEM stereo with a double din unit but not sure whether or not I need to bypass the stock amp since some say that the rear speakers will not work if I do not bypass it.
Many thanks for helping ^_^ and please tell me which harness do I need, cheers!
(New double din head unit is Alpine CDE-W223R)
Thanks!
Just bought my IS300 2 weeks ago, have already painted the headlights to black and installed an angel eye kit.
New wheels are coming in a few days and getting a TRD front bumper. Can't wait to install everything!
