Notes and caveats
No ground pin. LB160 carries no ground. The radio grounds from its case straight to the chassis.
* Pins 3, 8. No wire on these terminals.
One terminal is unnumbered. Between pins 13 and 4 a black wire leaves the head unit with no terminal number printed against it. It is omitted rather than guessed.
Speaker polarity. Not marked.
CD auto changer. On its own connector, RH170, not on LB160.
