Blue -White cable wire in iso ?

[spudboy6]

Coming from the cars loom to the iso , what is the blue and White wire for and what should I plug it in to ?

I plugged it in to the RCA / aerial is that correct or maybe this is causing my bad idle and stalling when coasting to an stop I once read ? Could be bollo*ck talk

Thanks people !

yeah, blue/white may well be the speed sensor feed from the car (can control volume on some stereos).

Disconnect it and see if problem goes away.
