Cruise control: worked when I pulled it off my car during an engine swap. $60
From my 1987 325is

Si board: honestly, unknown condition, I'm pretty sure it's fine, because I think I used it to test the condition of my gauges, but the board had no effect (the gauge was the problem). I would recommend changing the batteries though. Might as well since it's out.
$80

Pickup preferred around southern California, I'm in Riverside. Can ship at buyer's expense.
