Perfect for my Punch 200 amp. :-) Not so fast. The signal between the head unit and the amplifier is not a consumer type single ended signal (ground & signal). Instead Saab is using a pro type balanced signal (-signal & +signal). Do NOT connect -signal to signal ground on your amplifier! It might work to connect +signal to signal input on the amplifier, but I don't know where you can find a suitable signal ground as the power ground on pin 21 and 22 is probably way too noisy. The connector on the amplifier is as follows: One row with two fat red cables: 1 red +12V 2 red +12V 3 red line in right front + (balanced with pin 23) [1] 4 blue/white line in left front + (balanced with pin 24) [1] 5 grey line in right rear + (balanced with pin 25) [1] 6 yellow/white line in left rear + (balanced with pin 26) [1] 7 black/white speaker right subwoofer - [2] 8 grey speaker left subwoofer - [2] 9 n/c 10 n/c 11 black/white mute [3] 12 green head unit on [4] 13 n/c 14 red/white speaker right rear door + [2] 15 brown/white speaker left rear door + [2] 16 brown speaker right front door + [2] 17 blue speaker left front door + [2] 18 brown/red speaker right instrument panel + [2] 19 brown/white speaker left instrument panel + [2] 20 orange/white speaker center instrument panel + [2] One row with two fat black cables: 21 black ground 22 black ground 23 blue line in right front - (balanced with pin 3) [1] 24 red/white line in left front - (balanced with pin 4) [1] 25 brown/red line in right rear - (balanced with pin 5) [1] 26 orange/white line in left rear - (balanced with pin 6) [1] 27 black/green speaker right subwoofer + [2] 28 brown/red speaker left subwoofer + [2] 29 n/c 30 n/c 31 n/c 32 n/c 33 blue/white speaker right rear door - [2] 34 green/white speaker left rear door - [2] 35 green speaker right front door - [2] 36 red speaker left front door - [2] 37 grey speaker right instrument panel - [2] 38 brown speaker left instrument panel - [2] 39 blue speaker center instrument panel - [2] [1] 2V signal amplitute between each balanced pair, i.e. 3+23, 4+24, 5+25, and 6+26. [2] Speakers have no ground connection. [3] Below 1V after 1 second after ignition on. +12V for 10 seconds after ignition off. [4] +12V when head unit is on. -- G–ran Larsson Senior Systems Analyst hoh AT approve DOT se
