A power trunk lock solenoid installed where there was none before. It slipped right on, and bolted right down. All I need to do is run a wire to a switch inside the car.
Ok, so.. Long story short, our Canadian Tire had a $30 Eliminator 1.8W solar panel on sale for $10 this week.
I couldn’t resist picking one up. it came with a Cigarette Lighter adapter, a barrel-plug adapter, and battery clips. I’m sure I could think of a PIC project or three I could run off of Solar Power. Right now, It’s hanging in my windows by suction cup to charge a couple of 7Ah 12V Sealed Lead Acid batteries.
