Wiring Loom Issues - Calibra

Yup

car audio direct

you want an ISO adaptor :)

yup and you'll probably find it won't remember radio presets once you plugged the adapter in, you need to swap the wires so red goes in yellow and yellow into red, think that's right

yeah, you need what's called a harness adapter. it converts the loom from the standard vauxhall forward to the ISO standard, adopted now by most manufacturers. as Vamp says, you may find it won't remember various settings because of the way the loom is setup, so you might need to play about with the yellow and red live feeds until you get it to remember your presets...you may also find once this happens that your stereo operational even with the key removed and ignition off...only on a s*it vauxhall have i experienced this though...my old astra was s**te! lol

Thanks to all for answers. The problem is not actually the Connector on the car, somewhere down the line someone has plonked and ISO adaptor on. The problem is that the JVC head unit has a different plug configuration (2sets of 8 pins instead of 4 sets of 4) and I forgot to take off the JVC specific adaptor when I sold the car (spazzer!!!).

Anyhoo the nice guy in Halfords reckons they can get an ISO-to-JVC 16-pin from JVC so should be all OK. (I'll keep an eye on the presets issue though - thanks for that little gem)

Thanks again for your help!!!!!!!!
