I coverted Spectra with remote head to compact radio, and I need to aply +12v on emergency pin of accessory connector.
How I can do that on easy way, so that +12v on emergency, would not be on a external side of accessory connector?

You should install a jumper between pins 2 & 8 to ground the emergency line. +12v is not needed, except for the ignition sense pin.

Sorry, what I ment is that I need to aply +12V on ignition sense pin on accesory connector, and how to do that on easy way not on external side of connector but internal side, what to do somewhere inside a radio?!

The Dash, "compact' mount, radio needs IGN Sense on the 15 pin Acc connector to be able to power up, turn on, the radio. You also need the speaker leads along with the jumper on the EMERG pin to ground in the 15 pin plug.
The IGN Sense lead is usally tied thru a 1A fuse to the battery. The alternate connection is the switched IGN circuit in the car.
There are two jumpers in the A5 and A7 heads that can be configured for on/off control via the PWR switch without the IGN Sense lead connected to battery or switched IGN.
You still have to connect the Speaker and EMERG jumper to the 15 pin Acc connector in any dash mount configuration.

Don't forget about the command board jumper JU502. If JU502 is removed it reverses the polarity of the emergency sense (requiring the external emergency jumper to be removed). This is however a pain in the rear because you need a modified non-standard DB-15 accessory cable. The modified radio drawer and/or accessory cable usually cause problems later on, when someone else gets their hands on them and has to figure out what is wrong with them.

Wiill, did you mean JU1 and JU2 "in" on Control Head Board, and that will be O.K.?
Solution!

On Control Head Interconnect Bord, I connected pin 21 and pin 30, on P0502 and that is it!

asdfg,
I have done much the same for control stations that have to power up when 12 volts is applied to the radio's main DC connector. Much the same as the jumpers in the head do, but easier so any head will work.
